Product Detail
1、 Product Introduction
In the process of generating composite modified rubber asphalt, a high molecular organic compound is added to react chemically with sulfur, nitrogen and other heteroatoms in the asphalt, thereby suppressing the production of harmful substances. Adding a warm mixing agent reduces the construction temperature of the mixture during construction, reducing the emission of unpleasant gases generated by high-temperature oxidation of asphalt and volatilization of light components, fully in line with the national concept of green environmental protection.
2、 Characteristics of the product
A has good storage stability and is not prone to segregation
B Reduce production and construction environmental pollution
C has good performance indicators for rubber asphalt mixtures
