Rapid Curing Cutback Bitumen RC-250

Description of Cutback Bitumen RC-250

RAHA GROUP Bitumen RC-250 is Rapid curing (RC) cut-back asphalt consisting of penetration grade asphalt cement and diluent or cutter of rapid volatility.
Our Cutback Bitumen RC-250 complies with cutback petroleum asphalts of the rapid-curing type for use in the construction and treatment of pavements.

Cutback Bitumen RC-250 is a rapid curing cutback bitumen that contains 65% bitumen, is black in color, and is manufactured strictly as per ASTM D 2028M standard. 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 gasoline. 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.

Uses of CutBack Bitumen RC-250

Cutback agents are used to lowering 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 RC-250 consists of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction.

The cutback asphalt RC250 applying to waterproof of surfaces plug capillary voids, coat, and bond loose mineral particles.

Also, It uses in Priming of all non-bituminous road buses, provision of temporary surfaces(deviations).

This kind of bitumen is suitable to be used 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. 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. RC250 is used for pavement base and surfaces with dense-graded aggregate also for patching.

Application of Asphalt RC-250

From 0.6 litre per m² to 1.2 litre per m²

Guaranty and Safety of Bitumen RC-250

RAHA GROUP guaranty quality of cutback Bitumen RC250 with the arrangement of the international inspector. By checking the quality and quantity of the bitumen on each shipment during the loading to the vessel. Also controlling the production by QC team via batch test report before shipping.

Here are properties of RAHA Bitumen cutback RC250 which is classified by ASTM/EN15322:2009.

Packing of Bitumen RC250

Packing of cutback bitumen RC250 is in new thick steel drum on the pallet to prevent any leak inside of the container, IBC Tank, and also bulk in bitutainer.
