Cutback Bitumen SC-250

Cutback Bitumen Slow Curing 250 (SC-250) is a type of bitumen blended with a petroleum solvent to lower its viscosity for easier application at lower temperatures. It is classified as slow curing because the solvent used in the blend evaporates more gradually, giving the bitumen more time to penetrate the surface and bind with the materials it’s applied to.

Main Applications Of Cutback Bitumen SC-250

The main applications of Cutback Bitumen Slow Curing (SC-250) are in road construction, repair, and maintenance, particularly in situations where thicker layers of bitumen are required and cold application is preferred. SC-250 is commonly used in the following ways:

Prime Coating: Cutback Bitumen SC-250 is applied as a prime coat on granular or unbound base layers to prepare the surface for asphalt paving. Its higher viscosity allows it to penetrate deeper and enhance adhesion between the base and asphalt layers.
Surface Dressing: Cutback Bitumen SC-250 is used in surface dressing, where it is sprayed on a road surface and covered with aggregate to create a protective, durable surface. Its thicker consistency ensures better bonding in this application.
Cold Mix Asphalt: Cutback Bitumen SC-250 is used in cold mix asphalt for patching roads, repairing potholes, and addressing other surface defects. Its slow curing time allows for longer workability, which is especially useful in cold weather or remote locations where heating bitumen is impractical.
Gravel Road Stabilization: Applied to unpaved or gravel roads, Cutback Bitumen SC-250 stabilizes the surface by binding loose particles and increasing road durability. Its higher viscosity makes it effective in reinforcing and stabilizing roadways that experience heavy traffic or adverse conditions.
Dust Control: Cutback Bitumen SC-250 can be sprayed on unpaved roads and construction sites to control dust by binding dust particles together. Its slow curing time allows for longer-lasting dust suppression.
Crack Sealing: Cutback Bitumen SC-250 is also used to seal cracks in road surfaces, preventing water infiltration and extending the pavement's lifespan. Its higher viscosity ensures effective filling and sealing of larger cracks.

Cutabck Bitumen SC-250 is particularly suited for projects that require a thicker application of bitumen and where extended workability or deeper penetration is needed. Its slow-curing nature makes it an ideal choice for cold weather regions or projects in remote areas.
