Cutback Bitumen Medium Curing MC
Medium Curing MC Cutback asphalt is simply a combination of asphalt cement and petroleum solvent. In addition, like emulsions, cutbacks are used because they reduce asphalt viscosity for lower temperature uses (tack coats, fog seals, slurry seals, stabilization material).
The use of cutback asphalts is decreasing because of:
- Environmental regulations. Cutback bitumenasphalts contain volatile chemicalsthat evaporate into the atmosphere. Emulsified asphalts evaporate water into the atmosphere
- Loss of high energy products. We use The petroleum solvents require higher amounts of energy to manufacture.
Also cutback bitumen medium curing MC is simply a combination of asphalt cement and petroleum solvent. Cutback uses because they reduce asphalt viscosity for lower temperature uses (tack coats, fog seals, slurry seals, stabilization material).
MC bitumen is medium curing
Degree of liquidity developed in each case depends principally on the proportion of solvent to asphalt cement. To less degree, fluidity of cutback may affects by hardness of base asphalt. Fluidity result`s degree in several grades of cutback asphalt—some quite fluid at ordinary temperatures and others somewhat more viscous. More viscous grades may require a small amount of heating to make them fluid enough for construction operations.
MC grade designed for mixing with aggregates. Because these grades do not break immediately upon contact with aggregate, mixes using them can remain workable for extended periods of time and lend themselves to cold mix stockpiles. Cutback is said to “cure” as petroleum solvent evaporates away. The use of cutback asphalts is decreasing because of environmental regulations.
Medium curing (MC) asphalt cement uses medium diluents of intermediate volatility generally in the kerosene boiling point range (MC-30, 70, 250, 800, 3000).
Petroleum cutback asphalt
Cutback asphalts contain volatile chemicals that evaporate into the atmosphere. Emulsified asphalts evaporate water into the atmosphere.Loss of high energy products. Also by using petroleum solvents, factory needs higher units of energy. This is more expensive than water-emulsifying agents used in emulsified asphalts. It is restrict to patching materials for use in cold weather.
Cutback Bitumen MC-3000
Our Cutback Bitumen MC-3000 is medium curing cutback bitumen consisting of penetration grade bitumen blended with solvent to control its curing time. They type of solvent controls the curing time while the amount determines the viscosity of the cutback bitumen. The solvent usually used to manufacture a medium curing cutback bitumen is kerosene.
The advantage of cutback bitumen have over emulsions is a much higher residual bitumen percent, typically over 80% compares with over 40-65% for bitumen emulsions. The result is more bitumen left on the roadway after curing, for the same volume of binder applied.
Our MC-3000 Cutback Bitumen complies with the ASTM D2028-97 standards for construction and treatment of pavements.
Application of Cutback Bitumen MC-3000
Cutback bitumen MC-3000 is suitable for primer sealing and can also be used in the manufacturing of asphalt pre-mix. Cutback bitumen are used extensively in sprayed sealing applications, particularly in colder weather where they proved 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.
Packaging of Cutback Bitumen MC-3000
Our packing options depends on our client’s needs. It can come in bulk (in tanker) or in new thick steel drums on pallet.
