Cutback Bitumen MC-250 Description

In many places, Cutback Bitumen MC-250 use is restricted to patching materials for use in cold weather 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. Cutback MC-250 use 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.

Cutback bitumen MC-250 is dissolved of bitumen in solvents of kerosene. In many countries, kerosene and other volatile petroleum-derived products are added as a cutter or cutback agent to bitumen to reduce (or cutback) the viscosity of the bitumen. The mixture obtained may be called cutback bitumen.

Our MC-250 Cutback Bitumen complies with cutback petroleum asphalts of the Medium-Curing type for use in the construction and treatment of pavements as per ASTM D2028-97 reapproved in 2004. Cutback Grade Bitumen is normally used in spraying and in some mixing applications. Cutback Bitumen is penetration grade bitumen blended with a solvent such as kerosene, white spirit, gasoline, and naphtha, controlling the curing time. Cut back petroleum asphalts of the rapid curing type supplied by Huei Jie Oil Company are petroleum grade bitumen manufactured from the fractional / vacuum distillation of crude oil blended with a solvent. Bitumen supplied by Huei Jie Oil Company is produced from the vacuum residue (short residue) feedstock. Penetration Grade bitumens are specified by the penetration and softening point test. Designation is by penetration range only. The penetration grade bitumens have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature/ viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability, and application temperatures of bitumen. The cutback bitumen (Asphalts) supplied by Huei Jie Oil are blended from petroleum grade bitumen as stated herein

Cutback Bitumen MC-250 Applications

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-250 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-250 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.

MC-250 Packing

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.

MC-250 Safety

Refer to Safety Data sheets before use.
Transport, use and store at the lowest temperature possible.
Eliminate all potential ignition sources during application.
Avoid breathing vapors. Avoid contact with skin.
Always wear appropriate PPE including heat protection when used hot.
DO NOT allow product or washings to enter stormwater or sewer systems.

MC-250 Characteristics

Huei Jie Oil Company guarantees that the Medium Curing CutBack Grade MC-250 it supplies under its offers is produced in compliance to and is in conformity to ASTM D-2028-97 Rev 2004 and is compliant to the following specification requirements.
