| 摘 要： | 无机胶凝材料稳定粒料作为基层材料的干缩特性是影响其长期使用性能的重要因素之一。通过室内击实与干缩试验,研究HA S稳定粒料中的含泥量对其强度以及干缩特性的影响规律。采用回归分析方法,获得干缩应变和平均干缩系数与失水率的关系;同时采用灰色关联分析方法,论证了含泥量对HA S稳定粒料干缩特性(最大干缩应变和最大平均干缩系数)的重要影响。分析结果可为道路HA S固化剂稳定粒料基层设计和施工提供参考数据。

| Abstract: | Dry-shrinkage performance of inorganic cement stabilized aggregate base course is one of important factors which affects its long-term pavement performance.By using laboratory compaction and dry shrinkage tests,the effects of mud content on the strength and dry shrinkage performance of HAS stabilized aggregate are studied.Using the regression analysis method,the relationships between dry shrinkage strain or average dry shrinkage index and water-losing rate can be simulated.At the same time,by using the grey incidence analysis method,the important effects of mud content on the dry shrinkage performance of HAS stabilized aggregate are confirmed.The results provide reference data for the design and construction of HAS stabilized aggregate base course. |
