BS group Bitumen RC250 is Rapid curing (RC) 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. After application, the diluent evaporates, leaving asphalt cement to perform its function. RC–250 bitumen viscosity is between 250-500 CST. Cutback bitumen RC-250 is dissolved of bitumen in solvents of kerosene.
Typical properties of bitumen RC250
BS group guaranty quality of cutback RC-250 with arrangement of international inspector. By checking quality and quantity of bitumen on each shipment during loading to vessel. Also controlling the production by QC team via batch test report before shipping.
Here are properties of BS group Bitumen cutback RC250 which is classified by ASTM/EN15322:2009.

Applications
This kind of bitumen is suitable to be used in the construction and treatment of pavements (Single surface treatment, Multiple surface treatment, Sand seal) as per ASTM D2028-97 reapproved in 2004. Cutback Grade Bitumen is normally used in spraying and in some mixing applications.
Current common uses are in penetrating prime coats (on open surfaces) 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.
RC250 is used for pavement base and surfaces with dense-graded aggregate also for patching.
