Cutback Bitumen or Bitumen Medium Curing (MC)

Share this page with your friends: 

Cutback Bitumen or Bitumen medium Curing (Liquid Bitumen) is Bitumen that is dissolved in a solvent . Typical solvents include Naptha, gasoline and kerosene, white spirit etc. The type of solvent controls the curing time while the amount determines the viscosity of the Cutback Bitumen.The advantage Cutbacks 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.

Environmental regulations. Cutback asphalts contain volatile chemicals that evaporate into the atmosphere. Emulsified asphalts evaporate water into the atmosphere.
Loss of high energy products. The petroleum solvents used require higher amounts of energy to manufacture and are expensive compared to the water and emulsifying agents used in emulsified asphalts.

Bitumen Cutback MC30

In many places, cutback asphalt use is restricted to patching materials for use in cold weather cutback MC-30 is medium curing (MC) cut-back asphalt consisting of penetration grade asphalt cement and diluent or cutter of medium volatility. The diluent temporarily reduces the viscosity of the asphalt cement for ease of handling and application. After application, the diluent evaporates, leaving asphalt cement to perform its function Petrochemical Trade Cutback MC-30 conforms to the specifications of ASTM D2127 (Medium-Curing Asphalt) or AASHTO M82The major use for Petrochemical Trade Cutback MC-30 is in the road maintenance industry where it is used as a prime coat of the base course prior to placing of the bituminous surface course. Its purpose is to bind the granular material of the base course to the asphalt layer. Usual application is by spray using a distributor.

Bitumen Cutback MC70

Cutback MC-70 is medium curing (MC) cut-back asphalt consisting of penetration grade asphalt cement and diluent or cutter of medium volatility. The diluent temporarily reduces the viscosity of the asphalt cement for ease of handling and application. After application, the diluent evaporates, leaving asphalt cement to perform its function. Petrochemical Trade Cutback MC-70 conforms to the specifications of ASTM D2127 (Medium-Curing Asphalt) or AASHTO M82a) 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.
Damp-Proof Courses - Used as damp-proof membranes in concrete floors particularly for small repairs or where extensions are keyed-in to existing structures.

Bitumen Cutback MC250

Cutback MC-250 is medium curing (MC) cut-back asphalt consisting of penetration grade asphalt cement and diluent or cutter of medium volatility. The diluent temporarily reduces the viscosity of the asphalt cement for ease of handling and application. After application, the diluent evaporates, leaving asphalt cement to perform its function. Petrochemical Trade Cutback MC-250 conforms to the specifications of ASTM D2127 (Medium-Curing Asphalt) or AASHTO M82a) 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.
b) Damp-Proof Courses - Used as damp-proof membranes in concrete floors particularly for small repairs or where extensions are keyed-in to existing structures.

Bitumen Cutback MC3000

Cutback MC-3000 is a medium curing (MC) cut-back asphalt consisting of penetration grade asphalt cement and diluent or cutter of medium volatility.
The diluent temporarily reduces the viscosity of the asphalt cement for ease of handling and application. After application, the diluent evaporates, leaving asphalt
cement to perform its function.
Petrochemical Trade Cutback MC-3000 conforms to the specifications of ASTM D2127 (Medium-Curing Asphalt) or AASHTO M82a) 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.
b) Damp-Proof Courses - Used as damp-proof membranes in concrete floors particularly for small repairs or where extensions are keyed-in to existing structures.
