CUTBACK BITUMEN
Introduction of cutback bitumen
Cutback Bitumen, which is a low viscosity liquid that has been dissolved in a solvent. The major benefit of this form of bitumen is that it does not need to be heated before use. To function as a solvent, cutback bitumen is created by adding regulated quantities of petroleum extracts such as kerosene, naphtha, diesel oil, and furnace oil. Although these adhesive ingredients are included to reduce the requirement for pre-application heating, they will evaporate when the bitumen is applied. This procedure is used to temporarily reduce the viscosity of bitumen. Cutback bitumen is more suited to cold climates than the others.
After the solvent has evaporated, the binder reverts to its initial penetration level to bind the particles together. For the blending process, three kinds of solvents are used: slow-curing, medium-curing, and rapid-curing solvents. The kind of solvent used impacts the pace at which bitumen will cure when exposed to air. A solvent with rapid curing (RC) will evaporate quicker than one with medium curing (MC) and slow curing (SC). Curing pertains to the solvent’s evaporation rate, which affects the bitumen’s setting time.
The viscosity of cutback bitumen is influenced by the amount of solvent used; the greater the amount of solvent, the lower the viscosity of the cutback. Cutbacks are more malleable than penetration grade bitumen; they can be molded more readily. Cutback bitumen is simpler to utilize at lower temperatures since it requires less heat than penetration bitumen to liquefy.MC30 and RC250 are typical cutback bitumens. The letters in the name represent the curing activity of the solvent, while the number represents the viscosity of the binder.
Cutbacks contain a substantially greater residual bitumen percentage compared to emulsions, often between 80 and 90 percent as opposed to between 40 and 65 percent for bitumen emulsions. With the same amount of binder used, more bitumen is left on the road after curing.
WHAT IS CUTBACK BITUMEN?
Cutback bitumen is a form of bitumen created by combining bitumen with a solvent to make it less viscous and more fluid. The “cutting back” procedure makes it possible to utilize bitumen for a larger variety of purposes, such as the production of bituminous paints, varnishes, and sealants. Depending on the intended use of the cutback bitumen, the cutting-back solvent may either be a petroleum distillate or a vegetable oil. After the cutback bitumen is applied, the solvent evaporates, leaving the bitumen left to bond with the surface.

COMMON CUTBACK BITUMEN GRADES AND USES
- Cutback Bitumen MC30: This grade of cutback bitumen is often used as a prime coat, which is a thin coating that is placed to the base course of a road prior to the application of an asphalt layer. The MC30 grade is also used as a tack coat, which is a thin coating that is put to an existing road surface prior to the application of a fresh layer of asphalt.
- Cutback Bitumen MC70: This grade of cutback bitumen is similarly used as a prime coat and a tack coat; however, it has a greater viscosity than MC30, making it appropriate for usage in temperatures that are lower than those of MC30.
- Cutback Bitumen MC250: This grade of cutback bitumen is utilized for sealing and waterproofing applications since it has a greater viscosity than MC70.
- Cutback Bitumen RC30: This grade of cutback bitumen cures quickly and is utilized for tasks that demand a substance that dries quickly, such as patching and repair work.
- Cutback Bitumen RC70: This grade of cutback bitumen is also a kind that cures quickly and is used for repairing and maintenance work, in addition to the building of temporary roadways.
- Cutback Bitumen RC250: This grade of cutback bitumen is a kind that cures quickly and is used for patching and repair work, in addition to the building of temporary roadways.
- Cutback Bitumen SC70: This grade of cutback bitumen cures slowly and is utilized for situations where a longer curing period is necessary, such as in the building of airport runways and other high-stress applications.
- Cutback Bitumen SC250: This is a slow-curing grade of cutback bitumen and is used for situations where a longer curing period is necessary, such as in the building of airport runways and other high-stress applications.
In a nutshell, the choice of cutback bitumen grade is determined by the particular application as well as the desired performance criteria, which include the curing time, the viscosity, and the temperature range. To identify the right cutback bitumen grade for a particular project, it is crucial to confer with a competent engineer or construction specialist.
CUTBACK BITUMEN PROPERTIES
Cutbacks are more malleable than penetration grade bitumen, and they may be shaped in more creative ways because to this quality. Cutback bitumen is simpler to deal with at lower temperatures because it must be heated to a lower temperature than penetration bitumen in order to become liquid. This makes it more malleable.
cutback bitumen Applications
Priming is a technique that requires adding a binder with a low viscosity to an aggregate base that has been prepared but is often unbound. It is designed to be absorbed by the upper layers of the base and to produce a surface that can be “wetted” more readily by a bituminous coating that will come later. Although it is not a frequent technique, the primer will be able to manage dust while still allowing traffic to pass over it for a limited period of time. Primers are often applied at rates ranging from 0.5 to 1.4 L/m2 of surface area. Cutback bitumens that are acceptable for priming are also used for tack coatings, which are placed to an underlying surface to assist with the adherence of following asphalt layers. The normal rate of application is between 0.2 and 0.4 L/m2, depending on the product.
Prime Sealing
When temperatures are too low for an effective priming operation or when traffic is likely to disturb a primed surface before the final seal can be sprayed, a primer seal can be used to provide adequate protection for the pavement for periods of up to six to twelve months. This type of seal can be used in situations where temperatures are too low for an effective priming operation. Cutback bitumens that are in good enough condition to be used for primer sealing may also be put to use in the production of pre-mix asphalt, which is put to use in the repair of patches.
Spray Sealing
Cutback bitumens are used widely in sprayed sealing applications, especially in colder weather when their superior initial stone retention might be attributed to their reduced viscosity. Cutback bitumens are used extensively in sprayed sealing applications. A single coat of the necessary cutback bitumen is typically sprayed onto the prepped pavement before aggregate is placed down on top of it.
USES OF CUTBACK BITUMEN AND EMULSION BITUMEN IN VARIOUS ROAD MAINTENANCE SYSTEMS
Different methods of road maintenance make use of cutback bitumen vs emulsion bitumen in various capacities.
| System | Description & Uses | Recomende Product |
| SurfaceDressing | An application of binder on the road surface by a bitumen distributor followed by a covering of aggregates/chippings spread by a hopper gritter. Can be a single or double-layer surface dressing | Cutback: MC -3000 |
| Prime Coating | An application of binder on a granular base to prepare for an asphalt surfacing .Normally a slow setting emulsion or cutback is used for better penetration purposes to seal off the road base. The rate of application can vary from 0.4-1.4 liter/m2 | Cutback : MC-30 MC -70 |
| Tack Coating | A very light application of binder –hand or machine sprayed –to ensure bonding between the existing layer and the new overlay. The rate of application is normally between 0.25-0.7 liter/m2, depending on the surface being sprayed | Emulsion: K1-40 : RS-1K: RS-2K |
| Semi– Grouting /Penetration Macadam | An application of hot binder on a compacted layer of coarse aggregate | Emulsion : RS-3K : MC-3000 Other : Bitumen |
| Slurry Sealing | A maintenance technique where specially tailored emulsion, aggregates, water, and /or mineral filler is mixed in an on-site distributor and spread on an existing road surface at a thickness of 3-6 mm. It is both a preventive and corrective maintenance method for sealing of surface cracks, waterproofing asphalt surfaces and stopping oxidation | Emulsion: ALFA/SS |
| Fog Sealing /Mist Spraying | It is similar to tack coating in that is a very light application of diluted emulsion for renewal/rejuvenation of old asphalt surfaces. The emulsion is usually diluted to a concentration of about 25-30% binder and applied at a rate of 0.3-0.8 liter/m2 | Emulsion : K1-40 : SS-1K : ALFA |
