摘　　要：综合考虑以抗压强度和抗冻性能为控制指标,对混合料进行配合比试验,试验证明石灰含量为10%的混合料的抗压强度均能满足规范的要求;不同配合比的混合料均具有良好的抗冻性能。Comprehensively taking into amount as control index with compression strength and frost resistance,the test of mixture proportioning is caried out. Test proves that compression strength of mixture with lime content of 10 percent is capable of meeting the specification requirements. The mixtures with different proportionings have all a good host resistance.

关 键 词：配合比 抗压强度 煤矸石 底基层 抗冻性能
