浇筑式沥青混凝土技术性能测试试验研究

Test and Research on Technical Performance of Cast-in Asphalt Concrete

通过浇筑式沥青混凝土正交试验,初步优选出一组配合比,并在此基础上进行基本性能试验,对优选的配合比试件,测试其压缩性、水稳定性、渗透性等指标。结果表明,各测试指标均满足规范设计要求。由此更进一步了解了浇筑式沥青混凝土的工作性能,为解决沥青混凝土心墙施工及运行过程中的问题奠定了基础。

Through orthogonal test ofcast-in-placeasphalt concrete,a group of mix proportion is preliminarily optimized. On thisbasis,basic performance testsarecarried out to test thecompressibility, water stabilityand permeability of the optimum mix ratio specimens. The results show that they meet the design requirements of specifications and further understand the working performance ofcast-in- placeasphaltconcrete, soas to solve the problem ofasphalt concrete. The problems in theconstructionand operation of thecore wall laya good foundation.
