Description Cutback bitumen MC-800

Cutback bitumen MC-800 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. The reduction in viscosity of the bitumen aids the construction of seal coats in road pavements as the softened mixture wets the chips more easily.

The cutback agent evaporates from the seal coat, the cutback agent becoming a negligible component of the seal coat a few months after application. If significant amounts of the cutback agent remain in the seal coat an unwanted long-term softening effect may result. Our Cutback Bitumen MC-800 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.  Penetration Grade bitumen’s are specified by the penetration and softening point test.

The designation is by penetration range only. The penetration grade bitumen’s 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.

Application of Cutback bitumen MC-800

Cutback bitumen MC-800 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction. Furthermore cutback asphalt MC-800 applying to waterproofing of surfaces, plug capillary voids, coat and bond loose mineral particles. 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.

We use Kerosene as a bitumen cutback agent at different concentrations according to local conditions and requirements. Cutback bitumen is ideal for prime coat. Also it cold applied because of easy uses and no need to thinning and heating.

Also, the applications can be as follows:

• Prime Coat: Applied to the base course of a road to improve adhesion for subsequent asphalt layers.
• Patching: Used for repairing damaged road sections, especially in colder weather.
• Surface Dressing: Can be applied as a thin layer on the road surface and covered with aggregate for improved texture and water resistance.
• Waterproofing: Can be used for waterproofing surfaces like roofs, basements, and tunnels.
• Damp-proofing: Effective in preventing moisture penetration in concrete floors, especially for small repairs.

Cutback bitumen MC-800 Advantages

Cutback bitumen MC-800 has several advantages over other types of bitumen, including:

• Ease of handling: The reduced viscosity of cutback bitumen MC 800 makes it easier to handle and apply than regular bitumen.
• Quick curing time: The medium-curing nature of cutback bitumen MC 800 allows it to cure relatively quickly, making it ideal for use in applications where a quick turnaround time is required.
• Water resistance: Cutback bitumen MC-800 is highly water-resistant, making it an excellent choice for waterproofing applications.
• Adhesion: The excellent adhesion properties of cutback bitumen MC 800 make it ideal for use in road construction and sealing applications.
• Cost-effective: Cutback bitumen MC800 is more cost-effective than other types of bitumen, making it a popular choice for many applications.

Cutback bitumen MC-800 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.
