不同抗车辙剂对沥青混合料高温性能影响研究
Research on influence of different anti-rutting additives on high-temperature performance of asphalt mixture
摘要
Abstract
To analyze effects of different factors on high-temperature performance of asphalt mixture with anti-rutting additive, three different anti-rutting additives were selected to conduct Marshall test, rutting test and Hamburg wheel tracking test, all aimed to study effects of anti-rutting additive, content and mixture gradation on high- temperature performance and significance level of asphalt mixture by orthogonal test. The results show that different factors significantly influenced high-temperature performance of asphalt mixture, and the differences are remarkable, as follows: type of anti-rutting additive, content of anti-rutting additive, mixture gradation, while the significance level of different factors is affected by test method. The effect of PR in improving the high- temperature performance of asphalt mixture is best, followed by RA, and the effect of Duroflex is relatively poor. In addition, the improvement of high-temperature performance gradually diminishes with the increasing content of anti-rutting additive. The recommended combination of factors for best high-temperature performance of asphalt mixture is "PR anti-rutting additive+content is 0.45%+AC-16 aggregate gradation. The result provides reference for selection of anti-rutting additive, optimization of content with anti-rutting additive, and optimal high-temperature performance.关键词
