Product Detail
Product Introduction
SBS modified asphalt is a mixture of matrix asphalt and a certain proportion of SBS modifier. It is uniformly dispersed in the asphalt through shear, mixing, and other methods, and a dedicated stabilizer is added to form an SBS blend material. SBS modified asphalt is classified as I-A, 1-B, 1-C, 1-D in construction specifications, and high-speed SBS modified asphalt, used for interlayer bonding of heavy traffic roads and ultra-thin overlays. It is one of the products with the largest sales volume and the widest range of uses in our company.
Product Features
It has good anti rutting ability, good elasticity and toughness, which improves the anti fatigue ability of the pavement. It has good strain capacity on roads with large flow and heavy overload, which can reduce the permanent deformation of the pavement.
