Cutback Bitumen SC-70

Cutback Bitumen SC-70 (Slow Curing 70) is a type of bitumen that is blended with a petroleum solvent to reduce its viscosity and make it easier to apply at lower temperatures. Slow-curing cutbacks use oils like diesel or low-volatility solvents as the diluent, which evaporate more gradually compared to rapid-curing cutbacks, leaving behind the bitumen to bind with the aggregate.

Main Applications Of Cutback Bitumen SC-70

The main applications of Cutback Bitumen Slow Curing (SC-70) are in road construction, repair, and maintenance, especially in cases where cold application is preferred. Key uses include:

Prime Coating: Cutback Bitumen SC-70 is applied to granular or unbound base layers to prepare the surface for asphalt layers by improving adhesion.
Surface Dressing: It is sprayed on road surfaces and covered with aggregate to create a protective and durable layer for road surfaces.
Cold Mix Asphalt: Used in cold mix asphalt for road patching and repairing potholes, eliminating the need for heating the bitumen.
Gravel Road Stabilization: Cutback Bitumen SC-70 is applied to stabilize unpaved or gravel roads by binding the loose materials and enhancing road strength.
Dust Control: It is sprayed on unpaved roads and construction sites to reduce dust by binding loose particles.
Soil Stabilization: Cutback Bitumen SC-70 is used to bind soil particles and reinforce the ground, improving load-bearing capacity for foundations or temporary roads.
Crack Sealing: It is used to fill and seal cracks in pavements, preventing moisture ingress and prolonging pavement life.

These applications make Cutback Bitumen SC-70 suitable for cold weather regions, remote areas, and projects that require extended workability.

Various Packing Method for Cutback Bitumen SC-70

Packing cutback bitumen is an essential process to ensure its safe transportation, storage, and handling. The method of packing often depends on the type of cutback bitumen, the transportation method, and the end-use. Here are the various methods used to pack cutback bitumen:
