This bituminous mixture additives is black powder solid and made from several kinds of refined polymer through compounding,drying and pulverization.
Principle：It greatly improves the high temperature stability of asphalt pavement by surface adhesion, reinforcement(forming net surface effect), and the filling to elastic recovery of asphalt.and meanwhile improve the water stability and low temperature crack resistance and durability,also has the function of preventing the phenomenon of rutting, anti crack function, greatly delay the pavement damage and reduce the cost of repair, also providing the effective and practical and more economical methods through solving the asphalt pavement quality .
This series of products has 2 types :
SMT-28L（normal type）and SMT-100L（Refined type) .
SMT-100L with more better waterproof performance, can make the asphalt pavement more durable.
