CRMB is a product that enhances asphalt by modifying it with crumb rubber and natural asphalt, as well as Bismides chemicals. Natural asphalt contains high levels of asphaltene and nitrogen, which increase the asphalt’s viscosity, raise its softening point, and reduce its penetration. The chemically treated crumb rubber and Bismides are designed to quickly blend with the asphalt, providing additional binding strength, elasticity, and softening point. The rubber’s carbon content acts as an anti-oxidant, preventing the asphalt from aging and oxidizing due to exposure to sunlight.
