PMB 70 is a polymer-modified bitumen designed for enhanced performance in road construction and maintenance. It combines standard bitumen with polymer additives to improve elasticity, adhesion, and resistance to deformation. This modification results in a material that can withstand higher temperatures and heavy traffic loads, reducing the likelihood of rutting and cracking. PMB 70-2 is particularly suitable for use in areas with moderate to high temperatures and is commonly applied in highways, urban roads, and airport runways.
