AI Technical Summary
The existing coal liquefaction residue composite modified asphalt has poor compatibility with the base asphalt, resulting in high viscosity, poor fluidity and poor dispersibility, which makes it difficult to meet the paving requirements of road engineering. In addition, the utilization rate of waste tires is low and environmental pollution is serious.
Composite modified asphalt, which uses desulfurized rubber powder or activated rubber particles with better compatibility with base asphalt, is prepared through shearing and development processes to improve its deformation resistance, high-temperature performance and low-temperature performance, making it suitable for heavy traffic sections.
It significantly improves the deformation resistance and low-temperature performance of composite modified asphalt, extends the service life of roads, reduces the amount of base asphalt used, increases the utilization rate of waste tires, and solves the problems of asphalt resource shortage and environmental pollution.
