Cutback bitumen MC-3000 is dissolved of bitumen in solvents of kerosene. In many countries, kerosene and other volatile petroleum-derived products are added as a cutter or cutback agent to bitumen to reduce (or cutback) the viscosity of the bitumen. The mixture obtained may be called cutback bitumen. The reduction in viscosity of the bitumen aids the construction of seal coats in road pavements as the softened mixture wets the chips more easily. The cutback agent evaporates from the seal coat, the cutback agent becoming a negligible component of the seal coat a few months after application. If significant amounts of the cutback agent remain in the seal coat an unwanted long-term softening effect may result. Our Cutback Bitumen MC-3000 complies with cutback petroleum asphalts of the Medium-Curing type for use in the construction and treatment of pavements as per ASTM D2028-97 reapproved in 2004. Cutback Grade Bitumen is normally used in spraying and in some mixing applications. Cutback Bitumen is penetration grade bitumen blended with a solvent such as kerosene, white spirit, gasoline, and naphtha, controlling the curing time. Cut back petroleum asphalts of the rapid curing type supplied by RAHA OIL are petroleum grade bitumen manufactured from the fractional / vacuum distillation of crude oil blended with a solvent. Bitumen supplied by RAHA OIL is produced from the vacuum residue (short residue) feedstock. Penetration Grade bitumens are specified by the penetration and softening point test. The designation is by penetration range only. The penetration grade bitumens have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature/ viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability, and application temperatures of bitumen. The cutback bitumen (Asphalts) supplied by RAHA OIL are blended from petroleum grade bitumen as stated herein.
EXPLANATIONS ABOUT CUTBACK BITUMEN MC-3000
Cutback Bitumen MC-3000 is a type of dissolved Bitumen. To produce this type, solvent oils such as kerosene are used in order to change bitumen into dissolved bitumen or liquid pitch, so that, during the consumption process, the solvent oil evaporates and bitumen residue to obtain the desired adhesion. In many countries, kerosene and other volatile petroleum-derived products are added as a cutter or cutback agent to bitumen to reduce (or cutback) the viscosity of the bitumen. The mixture obtained may be called cutback bitumen. Medium curing is the most common category in cutback bitumen, among which, MC-3000 grade has the highest demand. MC-3000 is a medium curing cutback bitumen that contains 80% bitumen and has the lowest viscosity among all grades. It is black in color and is manufactured strictly as per the ASTM D 2027M-13 standard. After application, the diluent evaporates, leaving asphalt cement to perform its function. MC-3000 bitumen viscosity is between 3000-6000 CST. Its commonly used as a Prime Coating. It is homogeneous and will not foam (as observed visually) when heated to application temperature. MC-3000 is medium curing (MC) cut-back asphalt consisting of penetration grade asphalt cement and diluents or cutter of medium volatility. The diluents temporarily reduce the viscosity of the asphalt cement for ease of handling and application. Cutback MC-3000 use in the road maintenance industry where it is used as a prime coat of the base course prior to placing the bituminous surface course.
USES OF CUTBACK BITUMEN MC-3000
Cutback asphalt is an asphalt cement that has a solvent or distillate such as gasoline, diesel fuel, kerosene, or naphtha added to make the asphalt liquid at ambient temperatures and improve its ability to coat aggregates. Two letters followed by a numerical digit designate or name a cutback asphalt. Cutback asphalt can contain between 12 and 40 percent distillate. The high demand for the distillates to be used in energy applications and ever-increasing air quality regulations have caused a steady decline in the use of cutback asphalt. Cutback agents are used to lowering the viscosity of bitumen when it is applied as a primer to the surface of a road pavement aggregate base course or substrate. Kerosene is used as a bitumen cutback agent at different concentrations according to local conditions and requirements. The cutback bitumen is ideal for prime coat and cold applied because of easy uses and no need to thinning and heating. Cutback bitumen MC-3000 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction. The cutback asphalt MC3000 applying to waterproofing of surfaces, plug capillary voids, coat and bond loose mineral particles. Current common uses are in penetrating prime coats and in producing patching or stockpile mixtures. Cutback asphalt used in mixing with aggregate will usually contain an adhesion agent to assist in the coating of the aggregate surface. The reduction in viscosity of the bitumen aids the construction of seal coats in road pavements as the softened mixture wets the chips more easily. The cutback agent evaporates from the seal coat, the cutback agent becoming a negligible component of the seal coat a few months after application. If significant amounts of the cutback agent remain in the seal coat an unwanted long term softening effect may result

Meanwhile, Cutback Bitumen MC3000 are used as components for road maintenance industry where it is used as a prime coat of the base course prior to placing of the bituminous surface course. This type of Bitumen is most commonly used as an adhesive material between road foundation and asphalt coating, in the road construction industry which includes superstructure and foundation. Cutback Bitumen MC-3000 is used Priming of all non-bituminous road buses, provision of temporary surfaces(deviations) Also, Cutback Asphalt MC-3000 is suitable for primer sealing and can also be used in the manufacturing of asphalt pre-mix. Cutback bitumen is used extensively in sprayed sealing applications, particularly in colder weather where they proved improved initial stone retention due to their lower viscosity. Other uses include roofing as a waterproofing membrane and as an adhesive to stick chippings onto a flat, horizontal roof to minimize the effects of weathering from the sun.
APPLICATION OF CUTBACK ASPHALT MC-3000
Recommended Application Rate:
Uses: Cutback MC 3000 containing 80% Bitumen, is commonly used for surface dressing and semi grouting (Penetration Macadam). The process of priming involves applying a low viscosity binder to a prepared but usually unbound aggregate base. It is intended to be absorbed by the top layers of the base and provide a surface which is more easily wetted by a following bituminous covering. This is applied to an underlying surface to aid with the adhesion of the following asphalt layer. Cutback Bitumen is suitable for primer sealing and can also be used in the manufacture of pre-mixed asphalt, used in patch repairs. Cutback Bitumen is used extensively in sprayed sealing applications, particularly in cooler weather where they provide improved initial stone retention due to the lower viscosity. Usually a single application of cutback bitumen is sprayed on the primed pavement onto which aggregate is laid.
Flammable: Contains petroleum distillate. Avoid heat, flames and sources of ignition.
Prime and Tack Coating: The process of priming involves applying a low viscosity binder to a prepared but usually unbound aggregate base. It is intended to be absorbed by the top layers of the base and provide a surface more easily ‘wetted’ by a subsequent bituminous covering. The primer will be able to carry traffic for a short time (although this practice is uncommon) and help control dust. Generally, primers are applied at rates between 0.5 and 1.4 L/m2. Cutback bitumens suitable for priming are also used for tack coats, which are applied to an underlying surface to help with the adhesion of subsequent asphalt layer. A typical application rate is between 0.2 and 0.4 L/m2.
Prime Sealing: Where temperatures are too cool for an effective priming operation, or where traffic is likely to upset a primed surface before the final seal can be sprayed, a primer seal can be used to give adequate protection of the pavement for periods of up to 6 to 12 months. Cutback bitumens suitable for primer sealing can also be used in the manufacture of pre-mix asphalt, which is used in patch repairs.

Spray Sealing: Cutback bitumens are used extensively in sprayed sealing applications, particularly in cooler weather where they provide improved initial stone retention due to their lower viscosity. Typically, a single application of the appropriate cutback bitumen is sprayed onto the primed pavement onto which aggregate is laid.
