Elvaloy RET改性沥青混合料路用性能研究

Study on Pavement Performance of Elvaloy RET Modified Asphalt Mixture

通过车辙、低温弯曲、浸水马歇尔和冻融劈裂等试验,研究不同Elvaloy RET掺量改性沥青混合料的高温、低温和水稳定性能,全面对比和评价了Elvaloy RET掺量对基质沥青性能改善效果的影响,提出了Elvaloy RET工程用最佳掺量。研究结果表明:Elvaloy RET改性沥青混合料具有良好的路用性能。

Through wheel-tracking test, low-temperature bending test, immersed Marshall test and freeze-thaw splitting test, the performance of modified asphalt mixture with different contents of Elvaloy RET at high and low temperature and its water stability were studied, by which the impact of Elvaloy RET content on the property of the asphalt matrix was compared and evaluated, and the best content of Elvaloy RET in construction was proposed. The results show that Elvaloy RET modified asphalt mixture has good pavement oerformance.
