In many locations, the use of cutback asphalt is limited to patching materials for use in cold weather. The thinner temporarily reduces the viscosity of the asphalt cement for ease of handling and application. Cutback MC-30 is used in the road maintenance industry where it is used as a primary base layer coating prior to placing a bituminous surface. Its purpose is to stick the granular materials of the base course to the asphalt layer. Its usual application is by spraying using a distributor.
MC-30 cutback bitumen is dissolved in kerosene solvents. In many countries, kerosene and other volatile petroleum-derived products are added to bitumen as a cutting or reducing agent to reduce (or lower) the bitumen’s viscosity. The resulting mixture can be called cutback bitumen.
Our MC-30 bitumen conforms to medium-curing cutback petroleum asphalts for use in the construction and treatment of pavements in accordance with ASTM D2028-97, which was reaffirmed in 2004. Bitumen cutback is penetration grade bitumen which is mixed with a solvent such as kerosene, white spirit, gasoline and naphtha and controls the curing time. Cutback petroleum asphalts of the fast curing type supplied by Jay Pasargad Company are petroleum bitumens produced from fractional/vacuum distillation of crude oil mixed with a solvent. Bitumen supplied by J. Pasargad Company is produced from vacuum waste feed (short waste). Penetration grade bitumens are determined by penetration and softening point tests. The determination is based on the scope of penetration only. Penetration-grade bitumens have thermoplastic properties that make the material soft at high temperatures and hard at low temperatures. This unique temperature/viscosity relationship is important when determining performance parameters such as adhesion, rheology, durability and bitumen application temperature. Cutback bitumens (asphalt) supplied by Jay Pasargad are blended from the petroleum bitumens listed here.
Cutback agents are used to lower 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-30 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction.
The cutback asphalt MC-30 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.
This cutback bitumen bulk in the tanker and also in new steel and thick drum on the pallet to prevent all leak inside of the container.
Refer to Safety Data sheets before use.
Transport, use and store at the lowest temperature possible.
