    Cutback Bitumen Medium Curing MC

    Uploaded by

    Eng Venance Masanja
    Medium curing cutback asphalt, or MC bitumen, is created by combining asphalt cement with petroleum solvents. This reduces the viscosity of the asphalt for uses at lower temperatures. MC bitumen is designed for mixing with aggregates and remains workable for extended periods. However, its use is decreasing due to environmental regulations concerning volatile chemical emissions.

    Medium Curing MC

     Cutback bitumen Medium Curing MC


    Medium Curing MC Cutback asphalt (http://www.globallybitumen.com) is simply a combination of
    asphalt cement and petroleum solvent. In addition, like emulsion (https://pub-
    ltd.com/bitumen/bitumen-emulsion/)s, 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 bitumen (http://www.globallybitumen.com/index.php/cutback-


    bitumen/) asphalts contain volatile chemicals (https://pub-ltd.com/chemicals/chemical-products/) that
    evaporate into the atmosphere. Emulsi ed 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, uidity of cutback may affects by hardness of base asphalt. Fluidity result`s
    degree in several grades of cutback asphalt—some quite uid at ordinary temperatures and others
    somewhat more viscous. More viscous grades may require a small amount of heating to make them
    uid 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- (http://rahabitumen.com/cutback-bitumen-mc-30/)30, 70

    Cutback asphalts contain volatile chemicals that evaporate into the atmosphere. Emulsi ed 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
    emulsi ed asphalts. It is restrict to patching materials for use in cold weather.
