Research on the Low-Temperature Crack Resistance and Construction Technology of Asphalt Mixtures for Highways
This study mainly explores the effective method to improve the low-temperature crack resistance and construction technology of asphalt mixtures for highways.By the methods of field observation,laboratory tests and numerical simulation,this study analyzes the variation law of the performance of the asphalt mixture in the low-temperature environment and studies the influence of different construction processes on its performance.The re-sults show that the reasonable control of construction temperature,the optimization of compaction processes and the use of appropriate additives can effectively improve the low-temperature crack resistance of asphalt mixtures and reduce the incidence of pavement cracks.Based on this,during highway construction,we should pay attention to the performance of asphalt mixtures in the low temperature environment and take corresponding construction technology measures,so as to improve the quality and service life of the road surface.
