摘要

煤矸石是一种特殊的软质粗粒土，在中国堆存达70亿吨，年增加1.5亿吨。若煤矸石用做道路基层材料可行，则有助于减少煤矸石占地，降低污染环境。为此，拟定了10种不同配合比，进行了石灰粉煤灰综合稳定试验，测试了煤矸石混合料的无侧限抗压强度、抗压回弹模量及温缩系数等指标，并进行了分析，得到了石灰粉煤灰比为1：2及二灰含量约为30 %的初步配合比。结果显示煤矸石可以用于低等级道路基层和高等级道路底基层。

Abstract

Coal refuse

a kind of special softening coarse grained soil

has amounted to 7 billion tons throughout China; and with l50 million tons being produced annually. Not only plenty of lands are occupied

but also colliery wastes pollute the natural environments. The paper focuses on the use of coal refuses

concerning the feasibility of coal refuses as a road base materials. Coal refuse mixtures are tested with 10 different lime and fly-ash contents and different aggregate gradation. Unconfined Compressive strength modulus of resilience and temperature shrinkage coefficient are tested and analyzed. Mixture ratio is recommended by the research. Proper ratio of lime to fly-ash is 1:2

percentage of lime and fly-ash is 30 %. Preliminary results indicate that coal refuse can be used as a sub-base material of high-class road or base material of low-class road.
