Influence of Anti-Stripping Agent on the Performance of Asphalt Mixture in Southeran Xinjiang
Anti-stripping agent is often used to make up for the unstable lithology of aggregate in the process of asphalt road paving in southern Xinjiang,but it is not known whether the high temperature environment will resist the adverse effect of stripping agent.There-fore,by simulation of the climatic conditions in southern Xinjiang in laboratory,the changes of high temperature performance,low tem-perature performance and anti-fatigue performance of asphalt mixture under the climatic conditions of southern Xinjiang for a long time are studied.It is found that under the long-term action of the simulated environment,the addition of anti-stripping agent has an adverse effect on the high-temperature stability of asphalt mixture,in which the dynamic stability is reduced by 400 times/mm,the low-temperature cracking resistance is improved to a certain extent,and the maximum bending tensile strain increases by 22.2%.With the increase of test time,the anti-fatigue performance of asphalt mixture with anti-stripping agent is larger than that of matrix asphalt mixture.
