INTRODUCTION OF EMULSION BITUMEN
Emulsion bitumen is heterogeneous, two-phase systems comprised of two immiscible liquids, bitumen and water, which are stabilized by a third component, the emulsifier. The bitumen is spread throughout the continuous aqueous phase as discrete droplets, generally between 0.5 and 5 microns in diameter, that are kept in suspension by electrostatic charges. The first two groups of bitumen emulsions are by far the most significant in terms of volume:
The names cationic, anionic, and nonionic relate to the total particle charge on the bitumen droplet given by the emulsifier. If an electric charge is introduced through an emulsion containing negatively charged bitumen particles, the droplets will migrate to the anode; hence, the emulsion is referred to be anionic. In contrast, positively charged particles move to the cathode, and these emulsions are called cationic emulsions. Since bitumen droplets in nonionic emulsions are neutral, they will not migrate to either pole. Clay emulsions are examples of these nonionic emulsions. Initially, attempts were attempted to generate emulsions by merely mechanical methods, but it quickly became evident that although a dispersion might be formed by mechanical shear, the dispersion would not be stable without the presence of a third component, the emulsifier. Initially, organic acids found naturally in bitumen were used. The acids were transformed into soap and the dispersion was stabilized by the addition of sodium or potassium hydroxide to the aqueous phase.
WHAT IS EMULSION BITUMEN?
Emulsion Bitumen, commonly referred to as bitumen emulsion, is a combination of bitumen (a gooey, black, very viscous liquid or semi-solid form of petroleum) and water. An emulsifying agent is used to blend the two ingredients and produce a stable, homogeneous mixture. Emulsions may be anionic (negatively charged), cationic (positively charged), or nonionic (neutral).
Road building, paving upkeep, and waterproofing are just a few of the many uses for emulsion bitumen. Depending on the individual application and the intended result, it may be applied by spraying, brushing, or pouring. Emulsion bitumen has the advantage of being applied at lower temperatures than hot-mix asphalt, which makes it a more energy- and environmentally-friendly choice. Emulsion bitumen is often used for smaller-scale building projects since it is simpler to handle and transport than other types of bitumen.

EMULSION BITUMEN HISTORY
Emulsion bitumen, also known as bitumen emulsion, is a critical substance that revolutionized construction and infrastructure, establishing a new paradigm in roadway development. The history of this versatile product traces back to the late 19th and early 20th centuries, around the time when modern transportation infrastructure began to expand globally.
The birth of emulsion bitumen is tied to the expansion of asphalt roads and highways. As the demand for durable, flexible, and waterproof paving material increased, so did the necessity for a substance like bitumen emulsion. This substance is a complex mixture of bitumen, water, and an emulsifying agent, offering the required viscosity for effective road surfacing.
Though the production of natural bitumen dates back to ancient times, its emulsified form came into prominence during the early 20th century. The first patent for bitumen emulsion was granted in 1904 to Dr. Norman Seymore and his wife Isabel Seymore in the United States, marking a significant turning point in road construction history. Their invention was driven by the need for a substance that could effectively blend with aggregates, providing better adhesion and improved longevity to paved surfaces.
Since then, bitumen emulsion’s use has proliferated, bringing significant improvements in road construction. It made possible the construction of roads in challenging weather conditions, thanks to its water-resistant properties and ability to adhere well to damp surfaces. Its cold-applied nature also made it a go-to solution in regions with harsh weather conditions, where hot-mix asphalt was impractical.
The modern iteration of emulsion bitumen manufacturing employs advanced chemical processes, enhancing the emulsifying agent’s ability to disperse bitumen particles uniformly in water. This technical evolution has improved the stability, performance, and environmental footprint of the product.
Today, emulsion bitumen is a key element in road construction, maintenance, and rehabilitation processes. Its variants, including anionic, cationic, and nonionic types, cater to diverse application requirements, setting a benchmark for versatile and efficient road paving solutions.
Reflecting on the past and looking at the present, it is clear that the story of emulsion bitumen is one of innovation, resilience, and progress. As we continue to optimize our infrastructure, this resilient binder will undeniably continue to play a vital role in paving our way towards the future.
EMULSION BITUMEN OTHER NAMES
Emulsion bitumen is also referred to by a variety of other names, depending on the context, its composition, and its use. Here are some of the alternate terms for emulsion bitumen:
Bitumen Emulsion: This is a direct reversal of the term “emulsion bitumen” and is widely used across the industry.
Asphalt Emulsion: In the United States and some other regions, “asphalt” is often used interchangeably with bitumen.
Cold Mix Asphalt: This term is frequently used when referring to the use of emulsion bitumen in cold mix applications, where the bitumen emulsion is mixed with aggregate at ambient temperatures.
Tack Coat or Prime Coat: When emulsion bitumen is used as a preparatory layer between the existing road surface and an overlay, it is often referred to as a tack coat or prime coat.
Bituminous Emulsion: A more technical term, “bituminous emulsion” refers to the same substance as emulsion bitumen.
Liquid Asphalt: This term is sometimes used in reference to emulsion bitumen due to the liquid nature of the product, although it can also refer to other forms of liquid bitumen products.
Remember, these terms can vary by region and specific application, and it is essential to understand the context in which they’re used.
EMULSION BITUMEN HS CODE, CHEMICAL FORMULA AND CAS NUMBER
Emulsion bitumen, often referred to as asphalt emulsion, is a substance vastly utilized in road construction and waterproofing solutions due to its adhesion and waterproof properties. Its unique formulation is represented by the chemical formula (C5H9)n, mirroring its nature as a complex mixture of hydrocarbons.
Emulsion bitumen’s Harmonized System (HS) Code varies based on its specific type and use. Primarily, it falls under the code 2715, a category designated for “Bituminous mixtures based on natural asphalt, on natural bitumen, on petroleum bitumen, on mineral tar or on mineral tar pitch.” Specific sub-codes under this category detail further, clarifying the specific type of bitumen emulsion.
The CAS (Chemical Abstracts Service) Registry Number for bitumen is 8052-42-4. This number identifies it within the CAS system, a universally recognized database for chemical substances. However, note that emulsion bitumen is a product made of bitumen, water, and an emulsifying agent, so there isn’t a specific CAS number for it.
EMULSION BITUMEN COMPONENTS AND MATERIALS
Emulsion bitumen is a unique material that combines a few distinct components to create a substance with specific properties suitable for various applications in the construction industry, particularly road construction. Here are the key components of emulsion bitumen:
Bitumen: The primary component of emulsion bitumen is bitumen itself, a thick, black, highly viscous liquid or semi-solid form of petroleum. Bitumen contributes the adhesive and water-resistant properties that make it so valuable in construction.
Water: This is the secondary base component of the emulsion. It facilitates the distribution and application of the bitumen in its emulsified form.
Emulsifier: This is a vital ingredient in the emulsion bitumen recipe. It’s a surfactant (surface-active agent) that allows the bitumen and water, which are naturally immiscible, to remain in a stable emulsion. It does this by reducing the surface tension between the two, essentially allowing the bitumen to be dispersed throughout the water in tiny droplets.
Acid or Base: Depending on the type of emulsion bitumen (anionic or cationic), an acid or base is used in conjunction with the emulsifier to establish the necessary conditions for creating the emulsion.
Additional Additives: These might include polymers or other performance-enhancing additives that can improve the properties of the emulsion bitumen, such as its durability, flexibility, or resistance to particular environmental conditions.
The specific formulation of these components can vary, depending on the desired properties of the final emulsion bitumen product. Different applications might require different types of emulsion bitumen, each with their own specific balance of these components.
EMULSION BITUMEN TYPES
There are two distinct forms of bitumen emulsion:
Based on Time of Setting
When the bitumen emulsion is sprayed to the aggregate for roadwork, the water evaporates, leaving behind bitumen droplets. These droplets disperse over the aggregate, bond to one another, and gradually build strength.
On the basis of the time required for the vitamin emulsion to evaporate the water and for the particles to separate from the water, bitumen emulsion is further divided into three categories depending on setting time:
a) Slow setting emulsion
In this sort of emulsion, a specific type of emulsifier is utilized to slow the rate of water evaporation. This category of emulsifiers is rather stable.
b) Medium setting emulsion
When applied to aggregate, this form of bitumen emulsion does not crack. When fine mineral dust is combined with an aggregate emulsion mixture, the evaporation process begins.
c) Rapid setting emulsion
This form of bitumen emulsion degrades swiftly when it comes into touch with aggregate, aiding in fast setting and rapid curing.
According to Surface Charge
The components of bitumen emulsion are water and bitumen. Typically, a third component is added to a combination of water and oily substances to make it more stable, since the mixture of water and oily substances soon separates.
This third ingredient, known as an emulsifier, is employed to create a water-and-oil combination that is spread inside each other. In addition to reducing the tension between oil and water molecules, emulsifiers contain an electrical charge that influences the molecules of bitumen emulsion and leads to its classification as Cationic or Anionic.
- Anionic Bitumen Emulsion
- Bitumen Emulsion Cationic
The microscopic bitumen droplets in anionic bitumen emulsion are electronegatively charged. Electro positively charged bitumen droplets are present in cationic bitumen emulsion.
Between emulsions, cationic is the norm and most prevalent.
The selection of positive or negative recharge between emulsions is dependent on the mineral composition of the aggregate employed.

TABLES OF TYPES OF EMULSION BITUMEN
According to their setting time, both cationic and anionic bitumen emulsions are classified. Below is a table listing the numerous types of bitumen emulsion as well as their internationally recognized names.
EMULSION BITUMEN DURABILITY
Emulsion bitumen is highly durable and versatile, which contributes significantly to its widespread use in construction, particularly in paving and roadwork. Its durability can be attributed to the following characteristics:
Adhesion: One of the key aspects of bitumen emulsion’s durability is its adhesive property. It binds well with different types of aggregates, ensuring a solid and lasting bond that withstands wear and tear.
Water Resistance: Emulsion bitumen is highly resistant to water, which enhances its durability. This property helps protect the underlying road structure from water damage and contributes to the longevity of roads built with this material.
Flexibility: Unlike some other road construction materials, bitumen emulsion exhibits excellent flexibility. It can withstand temperature changes and slight movements without cracking, which improves its lifespan.
Resistance to Aging: Modern bitumen emulsions are manufactured with additives that improve their resistance to oxidative aging, a primary cause of road surface degradation. This makes them more durable over time.
Ease of Repair: If a road constructed with bitumen emulsion does develop damage over time, the affected area can be easily repaired or resurfaced, extending the road’s overall lifespan.
While emulsion bitumen offers notable durability, it’s important to note that the lifespan of any road also depends on factors such as the quality of the construction work, the underlying road structure, and the type and volume of traffic it endures. Furthermore, regular maintenance and timely repair work can significantly enhance a road’s durability.
EMULSION BITUMEN PRODUCTION PROCESS
In the manufacturing of bitumen emulsion, water is treated with an emulsifying agent and other chemicals before being put into a colloid mill with bitumen. The colloid mill fragments the bitumen into microscopic droplets. The emulsifier migrates to the asphalt-water contact and prevents the droplets from aggregating. Afterwards, the emulsion is pumped into a storage tank. To get the appropriate bitumen emulsion qualities, complex bitumen emulsions and a solid understanding of chemistry are needed. Bitumen and the kind and quantity of emulsifying agent are variables in the emulsion generation process. Anionic bitumen emulsions and cationic bitumen emulsions are the two most common classes of emulsions worldwide. The designation is determined by the emulsifying agent type used. Emulsifying agents are the chemicals required to stabilize the emulsion and maintain the “billions and billions” of bitumen droplets distinct from one another. These compounds are big organic molecules consisting of two separate components. These components are known as the “head” and “tail.” The “head” consists of a collection of atoms with chemically positive and negative charge regions. Because of these two charged regions, the head is referred to be polar (as in poles of a magnet). Due to its polarity and the composition of some of the atoms in this polar head, the head is soluble in water. The tail consists of a long chain organic group that is insoluble in water but soluble in other organic compounds, such as oils (bitumen). Thus, an emulsifying agent consists of a single molecule containing both water-soluble and oil-soluble components. The chemical’s emulsifying ability is a result of its unique property.
Bitumen emulsion is produced in two straightforward steps:
First, the water is combined with the suitable emulsifier and other chemical agents. The choice of emulsifier is determined by the ionic composition of the mixture.
In the second step, an emulsifier-water mixture is introduced to bitumen in a colloidal mill. The quantity of bituminous to be added is contingent upon the intended application of the bitumen emulsion. If it is employed for significant tasks, the percentage might vary from 60 to 70 percent.
The usual bitumen mixture ranges from 40 to 70 percent.
The colloidal mill reduces the bitumen to very minute droplets. The typical size of a bitumen droplet is around 2 microns. However, the droplets attempt to clump together and settle the liquid.
On the other side, the emulsifier generates a coating of surface charge around each bitumen droplet, which helps to maintain them apart and in a dispersed and suspended state. The mixture obtained from the colloidal mill is held in storage tanks and used as needed.
Breaking emulsion characteristics:
To facilitate application, emulsions exist. After application, water should evaporate, leaving asphalt cement behind. In a surface treatment, once emulsion and aggregate have been put to a road’s surface, the emulsion should “break,” leaving the asphalt cement to retain the aggregate. At that time, surface traffic may be permitted without aggregate loss. The kind of emulsion used has a significant impact on the rate of “break” of an emulsion. Nearly every surface has a net negative charge. This negative charge’s strength or intensity may vary from substance to material. As a result of this phenomena, anionic and cationic emulsions break apart differently.
In an application of anionic emulsion, droplets of asphalt that are negatively charged are applied to a negatively charged surface. All elements are mutually repellent. Only by the loss of water through evaporation can the emulsion split. As more water is lost via evaporation, the particles are pushed closer together until they can no longer be separated by a water layer. At this moment, droplets consolidate into bigger and larger drops, finally forming a film of bitumen and asphalt on the road. The following diagram illustrates the application:
During the application of cationic emulsion, positively-charged bitumen droplets are applied to a negatively-charged surface. The bitumen droplets are quickly attracted to the surface and begin to break apart upon contact. Evaporation contributes to the emulsion’s water loss. Thus, the cationic emulsion has two pathways for breaking and will shatter quicker than its anionic counterpart. The following diagram illustrates the application:
The purpose of a surface treatment is to seal the road against moisture penetration and to give a fresh skid-resistant surface, while allowing traffic to resume as quickly as feasible and retaining aggregate. Due to the chemistry of emulsions, they may respond differently under certain weather and application circumstances. If you have issues in any of these regions, it may be due to the weather, aggregate condition, or utilized emulsion.
The basic bitumen has also been diluted in bitumen emulsions in order to simplify application. Bitumen, water, and an emulsifier are processed in a high-speed colloid mill, which disperses the bitumen in the water. The emulsifier creates a system in which tiny droplets of bitumen comprising between 30 and 80 percent of the volume are suspended. The emulsion may be quickly reestablished by agitation if it separates during storage.
The low viscosity and workability of bitumen emulsions at room temperature make them excellent for use in road pavements and surface. This application needs deliberate breaking and setting. The emulsion must not break before they are spread on the road surface, but after they are in place, they should break fast so that the road may be used again without delay.
The following elements determine the stability of emulsions:
- Quantity and classification of bitumen emulsifiers.
- Evaporation rate of water.
- Bitumen amount.
- Bitumen globules size.
- Forces of mechanics.
- Sprays are used to administer the emulsions. Viscosity is a key problem in this situation. The mixture gets more viscous as bitumen concentration rises. When the percentage surpasses 60%, this is deemed sensitive.
Which substances make up the emulsion?
Asphalt (bitumen) and water are the key components of the emulsion. Emulsions are available in a variety of grades, but generally include 55 to 75% asphalt (bitumen). In addition to asphalt (bitumen) and water, asphalt emulsions comprise between 0.1 and 2% of an emulsifier or “soap” that serves to stabilize the emulsion. These soaps and detergents used for household cleaning and personal care are comparable to these soaps. The asphalt emulsions may also include trace quantities (1%) of additional substances, including pH (acidity) regulators and viscosity regulators.
The emulsifying agents are:
The most prevalent compounds obtained from wood are fatty acids and lignin, which combine with sodium hydroxide to create soap. In the presence of water, the soaps become negatively charged and produce “anionic” asphalt emulsions. A second category of emulsifiers, amines are generated from either wood acids (tall oils) or animal fats (tallow). These emulsifiers produce soaps that get positively charged in water to produce “cationic” asphalt emulsions.
Factors affecting setting of emulsions
The following elements impact the setting & curing of bitumen emulsion mixtures.
- Water absorption of aggregate
- The roughness of the aggregate’s surface
- Amount of mineral dust in aggregate
- Aggregate gradation
- Mineral content of aggregate
- The charge density on aggregate surface
- Type of emulsifier used & its amount
- Atmospheric state, climatic circumstances
- Wind speed and altitude
- Conditions of the building site’s drainage
The functionality of bitumen emulsion:
When bitumen emulsion is combined with aggregates used in road building, the emulsion destabilizes and the bitumen droplets fuse together, forming a strong adhesive bond that “glues” the aggregates together. The water evaporates, but the emulsifiers stay in the bitumen, where they serve a vital purpose by assisting the bitumen to adhere to the aggregate.

Advantages of Emulsion Bitumen Usage in Prime Coat and Tack Coat:
When it comes to prime and tack coat treatments, the use of emulsion bitumen offers a number of benefits to the user. To begin, as compared to the more conventional method of using hot mix asphalt, emulsion bitumen is a substance that is both safer and better for the environment. This is due to the fact that emulsion bitumen is mixed at lower temperatures, which in turn results in less emissions and use of energy. In addition, emulsion bitumen has outstanding bonding qualities, which leads to pavements that are both more robust and more long-lasting. The use of emulsion bitumen in the construction of pavements lowers the likelihood that the pavement would crack or rut, which leads to a longer lifespan for the pavement.
EMULSION BITUMEN PERFORMANCE
Emulsion bitumen’s performance is characterized by its diverse range of applications, ease of use, and the various advantages it offers in road construction and maintenance. Here’s a breakdown of emulsion bitumen’s performance:
Versatility: Bitumen emulsion is highly versatile, with different types suitable for various applications such as surface dressing, cold mix, tack coat, prime coat, slurry seal, micro-surfacing, and soil stabilization.
Cold Application: Bitumen emulsion can be applied at relatively low temperatures, which is a significant advantage in cold or wet climates where heating bitumen would be challenging or impractical. This allows for road work to continue throughout the year in many regions.
Environmentally Friendly: The process of using bitumen emulsion is considered more environmentally friendly than some traditional road construction methods, as it requires less energy (due to cold mixing) and produces fewer emissions.
Safety: Since bitumen emulsion is used at lower temperatures, it presents fewer risks related to burns or fire hazards compared to hot mix asphalt. It also releases less fumes, providing a safer environment for workers.
Good Adhesion: Bitumen emulsion provides excellent adhesion with aggregates, which is crucial for the construction of durable road surfaces.
Water Resistance: Bitumen emulsion provides a waterproof layer that protects the underlying road structure from water ingress, which can lead to premature failure of the road surface.
Fast Breaking: Bitumen emulsion breaks (the process where water evaporates, leaving behind the bitumen) quickly upon contact with aggregates or the road surface, allowing for quick work progression.
Compatibility: Emulsion bitumen is compatible with a wide range of aggregates and soils, making it suitable for various construction projects.
However, the performance of emulsion bitumen can be influenced by factors such as the specific formulation of the emulsion, the type and quality of the aggregates used, the application method, and the environmental conditions at the time of application. Proper storage and handling of bitumen emulsion are also crucial to ensure its optimal performance.
WHAT’S DIFFERENCE BETWEEN CUTBACK AND EMULSION BITUMEN?
Due to the kerosene component of reclaimed bitumen, there are significant concerns with its use, as shown below:
- Utilizing the fuel as a precious commodity.
- Environmental pollution caused by the solvent’s evaporation into the air and its penetration into the soil and subterranean waterways.
- Possibilities of kerosene combustion and inhalation while working.
Using water instead of kerosene in bitumen emulsion not only avoids the difficulties of cutback bitumen, but it also increases the bitumen’s efficiency and adhesiveness; this form of bitumen is also of superior quality and can be sprayed at lower temperatures with a bitumen emulsion sprayer.

EMULSION BITUMEN APPLICATIONS AND USES
Bitumen emulsion uses for the following purposes
• Emulsions are used in the building of bituminous roads. They are particularly useful for maintenance and patchwork repairs.
• The emulsion may be used even when it is pouring in damp conditions.
• Emulsions have also been used in soil stabilization, notably for stabilizing desert sands.
• An emulsion with a rapid setting time is suited for surface treatment and macadam building.
• The medium setting type is utilized for mixing coarse aggregates in advance.
• In the case of fine aggregates, the aggregate surface area is greater, necessitating a lengthy period of time for emulsion mixing. Therefore, it is preferable to use a slow-setting emulsion that allows ample time for homogeneous mixing.
• Bitumen emulsion Waterproofing: For waterproofing reasons, the bitumen emulsion can be simply sprayed on the wall, roof, floor, pool, restroom, and bathroom, as well as any other surface that we do not want to leak. It requires no heating and can be dispersed using a sweeper or sprayer.
• Bitumen emulsion paint: Bitumen emulsion paint is a protective coating that is emulsified and thixotropic. As the coating dries, it transforms into a protective film that is black and flexible. The completed film creates a robust barrier that prevents the passage of vapor.
EMULSION BITUMEN SAFETY TIPS
While emulsion bitumen is generally safer to handle than hot bitumen, certain precautions still need to be taken during its storage, handling, and application to ensure safety. Here are some safety tips:
Protective Equipment: Always wear appropriate personal protective equipment (PPE) when handling emulsion bitumen. This can include safety goggles, gloves, long-sleeved shirts, long pants, and safety shoes.

EMULSION BITUMEN INSTALLATION
The installation of emulsion bitumen involves several steps, varying depending on its application in road construction or maintenance. However, below is a general guide to the process:
Surface Preparation: Prior to application, the surface to be treated should be clean and dry. All loose material, dust, and debris should be removed. This can be done using brooms, air blowers, or other cleaning equipment. In the case of a new road, the substrate should be properly graded and compacted.
Application of Bitumen Emulsion: The emulsion bitumen is applied using a distributor truck equipped with a spray bar to ensure even distribution. The rate of application depends on the type of work and the specific characteristics of the bitumen emulsion and the surface.
Aggregate Spreading: Once the emulsion bitumen has been applied, aggregate is spread over the surface using an aggregate spreader. The size and type of aggregate used will depend on the specifics of the project and the type of bitumen emulsion being used.
Rolling: After the aggregate has been spread, it is compacted using a roller. This helps to embed the aggregate into the emulsion bitumen and ensures good contact between them.
Curing: The emulsion bitumen needs time to cure or set. During this process, the water in the emulsion evaporates, leaving behind the bitumen which binds the aggregate in place. The time required for curing will depend on various factors including the type of emulsion bitumen, weather conditions, and the thickness of the application.
Opening to Traffic: Once the emulsion bitumen has fully cured, the road can be opened to traffic.
It’s crucial to note that each application may require slight variations in the process. Furthermore, the quality and efficiency of installation depend on numerous factors, such as the type of bitumen emulsion, the quality of the aggregate, and the expertise of the installation team. Always follow the manufacturer’s guidelines and industry best practices to ensure a successful installation.
