F-PMB modifier is a direct-throw SBS asphalt modifier. The asphalt mixture prepared with it exhibits excellent anti-stripping performance and low-temperature crack resistance, and pavement durability is significantly improved. It can be used for asphalt modification to enhance the high-temperature and low-temperature properties of asphalt, especially greatly improving its low-temperature performance. It is applicable to the paving of intermediate and surface courses of expressways, permeable asphalt pavements, steel bridge deck surfacing, high-viscosity high-elasticity SMA pavements, stress absorption layers and other structures.
