Research and Application on Road Performance of Asphalt Mixture Reinforcing Agent

Abstract

Abstract: In order to comprehensively analyze the road performance of the reinforcing agent, the rutting test, low temperature bending test, submerged Marshall test, freeze-thaw splitting test and Hamburg rutting test (HWTD) were carried out on the AC-13 asphalt mixture with different mass fraction of reinforcing agent (0%, 0.2%, 0.35%, 0.5%), to test its high-temperature anti-rutting performance, low-temperature anti-cracking performance and water stability performance, and then compare it with the currently commonly used domestic anti-rutting agent A and SBS modifier from the perspectives of road performance, construction method and cost, and finally pass the test road supplementary verification. The test results show that the road performance of AC-13 asphalt mixture increases non-linearly with the increase of the dosage of reinforcing agent, and the recommended mass fraction is 0.35%. Compared with the SBS modifier,the asphalt mixture with reinforcing agent has a higher high-temperature anti-rutting performance. Although low-temperature anti-cracking performance is slightly lower, its cost is lower and the construction method is simpler. Compared with anti-rutting agent A, although the cost of asphalt mixture is slightly higher, its high temperature, low temperature and water stability are better. The use of test rode shows that the reinforcing agent has the advantages of simple construction method, convenient use and significant effect.
