AI Technical Summary
The existing ultra-thin mask technology has challenges in terms of durability and cost, and it is difficult to meet the Ministry of Transport's high-quality standards for high-viscosity asphalt. The stability and storage and transportation costs of high-viscosity modifiers are high, which has affected its promotion. and customer acceptance.
The high viscosity modified asphalt of rubber and plastic alloy is used, and its formulation includes matrix asphalt, modifier, cosolvent, stabilizer and coupling agent. Through specific mixing and heating processes, the colloidal instability index and modifier combination are controlled to improve the Viscosity and durability of asphalt.
It improves the high and low temperature performance, viscotility and durability of asphalt, meets the quality standards of the Ministry of Transport for high viscosity, reduces construction and maintenance costs, and enhances product stability and customer acceptance.
