What does MC-30 cutback bitumen mean?
MC-30 is a cutback bitumen which is a penetration bitumen asphalt blended with kerosene. Mc-30 means solvent is medium caring which express that the solvent will vapor at medium speed. The main applications of MC-30 cutback are prime sealing, prime coating, manufacturing of asphalt pre-mix and maintenance of the road.
How do I cut back bitumen?
Bitumen is ‘cutback’ by adding controlled amounts of petroleum distillates such as kerosene. This is done to reduce the viscosity of the bitumen temporarily so it can penetrate pavements more effectively or to allow spraying at temperatures that are too cold for successful sprayed sealing with neat bitumen.
What is MC 70 cutback bitumen?
MC-70 is a cutback bitumen which is a penetration bitumen asphalt blended with kerosene. Kerosene and other petroleum derived products are added as cutback agents reducing the viscosity. Mc-70 means solvent is medium caring which express that the solvent will vapor at medium speed.
What is MC in asphalt?
Medium-curing (MC) cutback asphalt cement is a combination of medium diluents of intermediate volatility, typically in the kerosene boiling point range, and asphalt cement.
What is MC-30 used for?
MC-30 is a type of medium curing cutback bitumen which is suitable for cold regions. It applies in road maintaining operations including tack coats and slurry seals. This type of liquid bitumen is constituted of a penetration grade bitumen and a petroleum based solvent.
What is MC-30 prime coat?
MC-30 is a medium curing cutback bitumen that contains 55% 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. Its commonly used as a Prime Coating.
What is a cut back bitumen?
Cutback bitumen is a petroleum product produced by diluting bitumen in petroleum hydrocarbon (Kerosene). The aim is to decrease the viscosity and to increase the penetration of bitumen on asphalt surface. In comparison with bitumen, cutback bitumen is sprayed on different layers of roads in a notably lower temperature.
What is cut back asphalt?
A cutback asphalt is simply a combination of asphalt cement and petroleum solvent. Like emulsions, cutbacks are used because they reduce asphalt viscosity for lower temperature uses (tack coats, fog seals, slurry seals, stabilization material).
What is the difference between MC-30 and MC70?
The difference between MC30 and MC70 As mentioned above, the main difference between MC-30 and MC-70 bitumen is their kinematic viscosity. For MC-30 the kinematic viscosity is 30 to 60 centistoke, but for MC-70 bitumen it is 70 to 140 centistoke.
What type of product is MC-30?
What is the meaning of 60 70 bitumen?
The penetration of Bitumen is used to measure its grade. It is reported as a penetration value of mm/10. Bitumen penetration grade 60/70 means the penetration value is in the range 60 to 70 at standard test conditions which commonly used as a Paving Grade.
What is the difference between MC-30 and RC cutback bitumen?
Unlike rapid curing cutback bitumen (RC), MC-30 has Kerosene as its solvent, which is safer than gasoline or naphtha in RC cutbacks. In comparison to bitumen emulsions, MC-30 cutback is a better primer than bitumen emulsions. Compared to many other grades of bitumen emulsion, it penetrates the compacted base more effectively.
What is MC30 used for in paint?
The main usage of mc-30 is in prime coating, cold mix asphalts and bitumen paints. Prime Coats: MC-30 bitumen is fully capable of bonding the base to the first layer of hot mix asphalt. This grade of MC cutback bitumen is a unique primer which provides temporary seal to prevent the surface water from penetrating through the surface.
Is cutback bituminous asphalt suitable for cold weather condition?
Due to their lower viscosity medium caring cutback bituminous asphalt is proper for cold weather condition. medium curing cutback petroleum asphalt supplied by bitumen supply manufacturing from vacuum distillation of crude oil blended with a petroleum solvent.
What is the difference between mc-250 and MC-30?
In comparison to MC-250, cutback MC-30 needs no heating in hot seasons. The main usage of mc-30 is in prime coating, cold mix asphalts and bitumen paints. Prime Coats: MC-30 bitumen is fully capable of bonding the base to the first layer of hot mix asphalt.
