Bitumen RC250
Introduction
Cutback bitumen RC250 is a type of bitumen dissolved in kerosene, widely used in construction for its viscosity-reducing properties. It uses packaging, and quality assurance of Cutback Bitumen RC250, highlighting its significance in various construction applications.
Properties of Cutback Asphalt RC-250
Asphalt RC-250 exhibits specific properties crucial for construction projects.
Viscosity Reduction
It significantly reduces bitumen viscosity, aiding in the construction of seal coats by facilitating chip wetting.
Uses in Seal Coats
It softens the mixture for seal coats, enhancing adhesion to chips in road pavements and ensuring durability over time.
Long-Term Effects
While the cutback agent evaporates from the seal coat, excessive residue may lead to unwanted long-term softening effects.
Uses of Cutback Bitumen RC-250
RC-250 finds versatile applications in construction due to its ease of use and effectiveness.
Primer for Road Pavements
It serves as a primer for road pavement surfaces, improving adhesion between layers and enhancing structural integrity.
Ideal for Cold Applications
RC-250 is ideal for cold applications, eliminating the need for heating and thinning, thus streamlining the construction process.
Waterproofing and Coating
Its waterproofing properties make it suitable for coating surfaces, plugging capillary voids, and bonding loose mineral particles.
Packaging and Quality Assurance
RC250 is packaged in new thick steel drums on pallets to prevent leaks during transportation. Quality assurance measures include international inspection and batch testing to meet standards like ASTM/EN 15322:2009.
