文章根据威乌支线海阳至即墨段第4合同段大粒径透水性沥青混合料试验为基础,经过认真细致的试验调整,成功配制了大粒径透水沥青碎石柔性基层混合料。通过对试验的认真总结,文章将试验的过程方法、调整方案等进行了详细的介绍。通过施工实践验证了调整后的空隙率和压实度是符合要求的。为大粒径透水沥青碎石柔性基层充分发挥其结构层特点创造了基础条件。
Based on the test of large particle size water-permeable asphalt mixture of section 4 of Haiyao-Jimo section of Wei-Wu branch, the flexible grass-roots mixture with large particle size pervious asphalt gravel was successfully prepared after careful and careful test adjustment. Through careful examination of the experiment, the article introduces the process method and adjustment plan of the experiment in detail. Through the construction practice to verify the adjusted porosity and compaction is to meet the requirements. The basic conditions for the large base of the permeable asphaltic detritus flexible base to give full play to its structural characteristics.
