摘　　要：将硅藻土掺配在沥青混合料中,可以改善沥青混凝土的性能,提高路面工程的质量。使用冻融劈裂试验,采用不同剂量的硅藻土来研究硅藻土对沥青混合料水稳定性能影响。试验结果表明硅藻土能较好地改善沥青混凝土水稳定性能,其最佳剂量为15%。Diatomite can improve the performance of asphalt concrete and enhanced the quality of road surface engineering. The freeze-thaw split test was undertaken in order to research the relation between diatomite dosage and water stability. According to the laboratory experimental results, approved that the diatomite can improve the water stability of asphalt mixture, and the opti dosage is 15 %.
