| 摘 要： | 通过系统测试粗集料指标和混合料动稳定度,研究了沥青稳定碎石骨架结构评价方法及其影响因素.测试了不同级配的沥青稳定碎石动稳定度,发现规范范围内不同混合料抗车辙能力有明显差距,且粗型沥青稳定碎石混合料抗车辙能力未必优于细型混合料;粗集料指标测试结果证实SSC及VCADRC与混合料动稳定度间有着良好联系,因而可利用VCADRC进行沥青稳定碎石粗集料设计或评价;利用均匀设计法进行的粗集料体积指标测试发现:单独一档粒径集料含量均与粗集料体积指标缺乏联系,整体的搭配才是关键.

| Abstract: | Through testing on coarse aggregate index and mixture dynamic stability,the evaluation method and influence factors of asphalt treated mixture's skeleton structure are studied.After testing of mixture with different aggregate gradation,it is found that the anti-rutting performance of mixtures within criterion is quiet different,and this performance of coarse mixture may not be better than fine mixture.It is confirmed that SSC and VCADRC have good correlation with mixture dynamic stability,so VCADRC can be u... |
