【摘要】 通过对沥青玛蹄脂碎石混合料SMA中的粗集料各粒径含量的调整,进行了一系列的室内试验。试验结果表明,粗集料中各粒径含量的变动对沥青混合料体积参数以及高温稳定性有重要影响,充分验证了粗集料含量对SMA骨架密实结构的显著作用,同时也验证了规范的合理性。更多还原

【Abstract】 According to adjusting the content of the coarse aggregate in the SMA stone matrix asphal a serious of tests have been done in this paper. The test results show that changing the content in coarse aggregate will bring an important effect to the volume parameter and compacity of rut-resistance of SMA mixture at high temperature. It proves that content of coarse aggregate gives birth to distinct function for the dense framework structure in the SMA and consequently testifies the rationality of criterion.更多还原
