CRMB is a modified bitumen material that combines the benefits of bitumen and rubber to produce a durable and flexible road construction material. It is a sustainable solution that recycles waste tires and reduces the environmental impact of road construction activities. CRMB can be used as a binder in asphalt concrete, which is the most common type of pavement used on roads and highways worldwide. It improves the performance of asphalt concrete by increasing its resistance to deformation, cracking, and aging.


The use of rubber in road construction dates back to the early 1900s when Henry Ford used rubberized asphalt to pave his automobile factory’s parking lot. However, the commercial use of rubberized asphalt did not become widespread until the 1960s when the first rubber-modified asphalt was produced in the United States. Since then, the use of crumb rubber in road construction has become increasingly popular, especially in countries with large quantities of scrap tires.


CRMB is also known as rubberized asphalt, rubberized bitumen, rubberized asphalt concrete, and asphalt-rubber.


Crumb Rubber Modified Bitumen (CRMB) presents a sustainable, high-performance choice for a variety of applications within the paving industry. This innovative road construction material blends scrap tires, also known as crumb rubber, with traditional bitumen, creating an enhanced binder with improved properties.

The components of CRMB chiefly consist of two main elements:

  1. Crumb Rubber: Derived from waste tires that are mechanically ground into small particles, typically between 0.6 to 0.8 mm. This recycling process not only reduces landfill waste but also harnesses the physical properties of rubber for enhancing the overall characteristics of bitumen.

  2. Bitumen: A highly viscous, sticky substance that’s a byproduct of petroleum refining. Known for its exceptional waterproofing and adhesive qualities, bitumen serves as the binder in CRMB, ensuring strong cohesion with aggregates in asphalt mixtures.

CRMB’s production involves blending these components under specific conditions—temperature, duration, and the amount of crumb rubber—to achieve the desired specifications.


The production process of Crumb Rubber Modified Bitumen (CRMB) or rubberized asphalt involves a series of well-defined stages, resulting in a product that optimally combines the advantageous properties of bitumen and crumb rubber. Here is a generalized process:

  1. Crumb Rubber Production: This is the initial phase where waste tires are mechanically ground into fine particles, creating the crumb rubber. The size of these particles typically ranges between 0.6 to 0.8 mm.

  2. Preliminary Blending: The crumb rubber is added to hot bitumen, usually at temperatures around 180°C. The high temperature is necessary for the rubber particles to swell and absorb the bitumen.

  3. Digestion Phase: The mixture is kept at the high temperature for a specific period, known as the digestion or reaction time. This period can vary between 1 to 2 hours and allows for the complete assimilation of the crumb rubber into the bitumen. During this process, the rubber particles swell, soften, and partially dissolve, creating a thicker, more viscous material.

  4. Final Blend: Following the digestion phase, the blend is stirred thoroughly to ensure the crumb rubber is evenly dispersed within the bitumen. This can be achieved by using high-speed shear mills.

  5. Filtration and Storage: The CRMB is filtered to remove any large, undissolved rubber particles. It is then stored at high temperatures to prevent separation before use.

  6. Use in Asphalt Mixture: The final CRMB product is mixed with aggregate material (stones, sand, etc.) to create the asphalt mixture that is used for paving.

Please note that the specifics of the production process may vary depending on the required properties of the CRMB, local regulations, and the technology available. Regardless of these factors, the goal is always to produce a superior pavement binder that can resist deformation, cracking, and weathering more effectively than conventional bitumen.


Crumb Rubber Modified Bitumen (CRMB) is an innovative form of bitumen, fortified by the inclusion of crumb rubber, which are finely ground particles extracted from waste tires. This unique combination boosts the performance and durability of bitumen, significantly enhancing road longevity. The varied grades of CRMB, differentiated by the rubber content and the production method, are specifically designed for distinct climates, road networks, and traffic volumes.

The three primary grades of CRMB are:

  1. CRMB 60: Tailored for warm climates, this grade blends bitumen with crumb rubber to enhance the elasticity of bitumen and increase its softening point, making it more resistant to high temperatures. It consequently reduces the risk of rutting and heat-related damage to the road surface.

  2. CRMB 55: This grade is suitable for general climates where temperatures fluctuate considerably throughout the year. It ensures optimal performance under a range of temperatures and is ideal for a variety of road construction projects, including highways, urban roads, and residential streets.

  3. CRMB 50: For colder climates with frequent sub-zero temperatures, CRMB 50 is the preferred choice. This formulation maintains flexibility at lower temperatures, thereby reducing the likelihood of thermal contraction-induced cracking. The added crumb rubber enhances the bitumen’s resistance to cold-temperature cracking and thermal fatigue.

Additionally, CRMB is available in different types based on the rubber content:

  1. Type A CRMB: Comprising 18-22% rubber, it’s produced by adding dry crumb rubber to hot bitumen. This type is ideal for high-traffic roads and highways, where the pavement must withstand heavy loads and extreme weather conditions.

  2. Type B CRMB: Contains 12-16% rubber and is produced by integrating wet crumb rubber with hot bitumen. It’s suitable for low-traffic roads and pavements, where the pavement must endure moderate loads and weather conditions.

  3. Type C CRMB: Comprising 6-10% rubber, this type is generated by adding wet crumb rubber to cold bitumen. It’s appropriate for thin pavements such as bike lanes and footpaths, where the pavement needs to be flexible and resilient.

CRMB can be procured in two forms: wet mix and dry mix. Wet mix CRMB is created by adding wet crumb rubber to hot bitumen and thoroughly amalgamating the components. Dry mix CRMB, on the other hand, is created by adding dry crumb rubber to hot bitumen and blending the mixture using a high-speed mixer.

The various grades, types, and forms of CRMB have a multitude of applications in road construction, determined by the pavement’s design, traffic volume, and climate conditions. High-traffic roads usually employ Type A or wet mix CRMB for its homogeneous and durable mixture. Conversely, low-traffic roads opt for Type B or dry mix CRMB due to its ease of handling and storage. Type C CRMB is typically used for thin pavements like bike lanes and footpaths, where flexibility and durability are crucial.

The production of CRMB can be achieved using two methods: the wet process and the dry process. Both involve blending crumb rubber with hot bitumen in a high-speed mixer. The wet process employs wet crumb rubber, whereas the dry process uses dry crumb rubber ground into a fine powder. The resulting CRMB is stored in a heated storage tank and transported to the construction site in insulated tankers, ensuring its optimal quality and performance for the specific application.


CRMB must meet specific specifications to ensure its quality and performance in road construction. The specifications may vary depending on the country and the project requirements, but the most common ones are as follows:

  • Penetration: the depth in tenths of a millimeter to which a standard needle will penetrate the CRMB sample under specified conditions of temperature and loading.
  • Softening point: the temperature at which the CRMB sample softens and deforms under specified conditions of heating.
  • Viscosity: the resistance of the CRMB sample to flow under specified conditions of temperature and shear rate.
  • Elastic recovery: the percentage of the original deformation that the CRMB sample recovers after being subjected to a specified deformation and relaxation cycle.
  • Fatigue life: the number of load repetitions that the CRMB sample can withstand before failure under specified conditions of temperature and loading.

The installation of Crumb Rubber Modified Bitumen (CRMB) largely follows the same procedure as traditional bitumen, with a few added steps to ensure the unique properties of the material are fully utilized. Below is a generalized process:

  1. Material Preparation: First, the CRMB is prepared according to the specifications of the project. This involves creating a mixture of CRMB and aggregates, which include materials like stones and sand.

  2. Heating: The CRMB mixture is heated to a certain temperature before application, usually around 160 to 170°C. It’s crucial to maintain this temperature range to prevent the premature cooling of the mixture, which can affect its workability and the quality of the finished surface.

  3. Transportation: The heated CRMB mixture is then transported to the construction site. Again, it’s essential to maintain the mixture at the proper temperature during transport.

  4. Placement: Upon arrival at the site, the mixture is placed on the prepared surface using a paving machine. The CRMB mixture is spread evenly across the area to be paved.

  5. Compaction: After placement, the mixture is compacted using rollers to ensure a uniform, dense surface. Proper compaction is crucial to the performance and longevity of the road. This process must be completed before the mixture cools and hardens.

  6. Curing: Finally, the paved surface is left to cure and harden. This can take a few hours to a few days depending on the specific mix and environmental conditions.

The successful installation of CRMB requires careful planning and execution. From the accurate preparation of the CRMB mixture to maintaining the proper temperature during transportation and installation, every step of the process plays a role in achieving a high-quality, durable road surface. It’s also worth noting that different projects may require specific installation techniques or additional steps based on local conditions and regulations.


Maintenance for Crumb Rubber Modified Bitumen (CRMB) roads largely parallels that of traditional asphalt pavements, although the improved properties of CRMB may lead to less frequent maintenance interventions. Here are a few key aspects of maintenance for CRMB roads:

  1. Routine Inspections: Regular inspections are crucial to identify early signs of distress such as rutting, cracking, or potholes. Timely identification and repair of these issues can prevent more significant damage and costly repairs.

  2. Surface Treatments: Surface treatments like seal coating can help preserve the surface of the road and extend its lifespan. These treatments can provide a protective layer, helping to resist weathering and oxidation, and maintain surface texture for skid resistance.

  3. Crack Sealing: Despite CRMB’s enhanced resistance to cracking, any cracks that do appear should be promptly sealed. This can prevent water from infiltrating into the pavement structure and causing more extensive damage.

  4. Pothole Repairs: Similar to cracks, potholes can be more effectively repaired if they are addressed quickly. Potholes in CRMB pavements can be patched using a suitable bituminous material.

  5. Resurfacing or Overlay: If the CRMB road shows signs of significant wear or distress, it may be necessary to apply a new layer of asphalt (an overlay) or to completely resurface the road. This typically involves removing the top layer of the existing pavement and replacing it with a new layer of CRMB.

  6. Drainage Maintenance: Ensuring proper drainage is crucial to prevent water-related damage. This includes keeping ditches, culverts, and storm drains clear of debris and making sure they are functioning correctly.

  7. Routine Cleaning: Regular sweeping can remove debris that may potentially damage the road or lead to drainage problems.

While CRMB roads often exhibit superior performance and longer service lives compared to traditional bitumen pavements, regular maintenance is still essential to maximize their lifespan and keep them in good condition. The specific maintenance needs and schedule will depend on the exact composition of the CRMB, the local climate, the volume and type of traffic, and other factors.


Crumb Rubber Modified Bitumen (CRMB) is known for its enhanced durability compared to traditional bitumen, making it an excellent choice for road construction, particularly in regions experiencing extreme weather conditions or high traffic volume. This increased durability stems from several unique properties of CRMB:

  1. Enhanced Elasticity: CRMB exhibits superior elasticity due to the incorporation of crumb rubber. This allows it to better accommodate the contraction and expansion caused by temperature fluctuations, reducing the likelihood of cracking and rutting.

  2. Increased Resistance to Deformation: High temperatures and heavy traffic can cause road surfaces to deform, leading to rutting. The increased rut resistance of CRMB contributes to its superior durability as it withstands deformation under these conditions.

  3. Superior Aging Properties: CRMB has improved aging properties. The crumb rubber slows down the oxidation process of the bitumen, which helps prevent brittleness and maintains the pavement’s flexibility over time.

  4. Water Damage Resistance: The crumb rubber within the CRMB creates a tighter, more flexible binder-aggregate matrix, which improves resistance to water damage and stripping, hence prolonging the service life of the pavement.

  5. Fatigue Resistance: CRMB’s enhanced elasticity also improves its resistance to fatigue cracking, a common type of distress in asphalt pavements subject to repeated loads.

These beneficial properties translate to reduced maintenance costs, longer road life, and improved driving conditions, making CRMB an environmentally friendly and cost-effective option for road construction projects. The specific durability of CRMB will vary depending on several factors including the precise formulation of the CRMB, the design and construction of the pavement, and the specific conditions (traffic, climate, etc.) to which the pavement is exposed.


The performance of Crumb Rubber Modified Bitumen (CRMB), or rubberized asphalt, greatly surpasses traditional bitumen in several key areas. Its unique properties make it a preferred material for road construction projects, offering enhanced functionality under various conditions:

  1. Elasticity: CRMB possesses greater elasticity due to the incorporation of rubber particles. This elasticity allows it to recover after being deformed by heavy traffic or temperature changes, reducing the likelihood of permanent deformation or rutting.

  2. Resistance to Cracking: The enhanced flexibility of CRMB reduces its susceptibility to both low-temperature cracking (caused by contraction in cold weather) and fatigue cracking (caused by repeated traffic loads).

  3. Thermal Stability: CRMB maintains its physical properties over a broader temperature range compared to traditional bitumen. This makes it suitable for regions with extreme temperatures, and it’s less likely to soften excessively in high temperatures or become brittle in low temperatures.

  4. Rutting Resistance: Under heavy traffic loads or high temperatures, conventional bitumen might form ruts or grooves. CRMB offers higher resistance to this form of road distress, enhancing road safety and longevity.

  5. Reduced Noise Pollution: CRMB pavements have been observed to reduce tire-road noise, making it an attractive solution for urban areas or highways near residential zones.

  6. Increased Skid Resistance: Asphalt made with CRMB often has a higher skid resistance, which can lead to improved road safety, particularly in wet conditions.

  7. Durability: Thanks to its superior resistance to common forms of road wear and distress, CRMB pavements generally have a longer service life. This leads to lower lifecycle costs for road infrastructure.
