Application Of Anti-rutting Agent In Heavy Traffic Road

In this paper, heavy traffic conditions, high temperature stability to add anti-rutting agent asphalt mixture, water stability and low temperature performance a study, the main conclusions are as follows:① relying on engineering analysis of the sections of the axle load situation, think there is heavy traffic will lead to increased pressure on the road, so that the pavement premature destruction.② consider overload factor under load 0.4MPa, 0.7MPa, 1MPa conditions, triaxial repeated load permanent deformation test, the test conclusion shows that the dual role of temperature and load, will produce asphalt pavement rutting, temperature and load increased stress can exacerbate the depth of the rut, but also appears to reduce the time rut.③ the paper has systematically compared the SBS modified asphalt AC13, the AC13 ordinary asphalt and Ken Terai and two anti-rutting agent PR.PLASTS were four different dosage under the conditions(8 ‰, 6 ‰, 4 ‰ and 2 ‰) of water stable performance, low temperature performance and high temperature stability, through the analysis of experimental results can be clearly seen that the anti-rutting agent can not only increase the impact of the anti-rut in terms of asphalt, the mix of low-temperature stability and water stability properties all have different degrees of improvement.④ with anti-rutting agent instead of SBS in SMA mixture into mixing were done unmodified asphalt SMA, SMA SMA after three kinds of SBS modified asphalt and modified with anti-rutting agent comparison test, the results of tests conducted by analysis shows that the anti-rutting agent for high-temperature performance and performance aspects of SMA asphalt mixture of water stability has a relatively good improvement. SBS can almost reach the level, although low in terms of stability, although compared to SBS modified has improved to some extent, but the effect is not as good as SBS, therefore, sum up the anti-rutting agent replace SBS modifier mixed performance materials is feasible.⑤ Compare AC20 mixture in two anti-rutting agent(Ken Streuli and PR.PLASTS) are two high-temperature stability in the amount of mixing under(3 ‰, 4 ‰) and low temperature performance and water stability, given The optimum dosage of anti-rutting agent.⑥ with the test results are given in the top layer of asphalt suitable addition ratio mix of anti-rutting agent, and gives pavement structure suitable for heavy traffic.
