摘　　要：通过对红砂岩和石灰岩集料掺配后进行磨光试验、混合料配合比设计、高温、低温及水稳性的验证试验,探究了不同掺配比例下(红砂岩)对集料磨光值、混合料各项性能的影响,并对主要影响因素进行了分析,得到了将红砂岩按一定比例(>25%)掺配于石灰岩中,可以提高混合料路用性能的结果。In this paper, the experiment of polishing, mixing ratio design, high temperature, low temperature and water stability test are carried out, after the blending of red sandstone and limestone. The effects of different blending ratio （red sandstone） on the polis- hing value and the properties of the mixture were explored, And the main influencing factors were analyzed. It got the conclusion that the red sandstone in a certain proportion （ 〉 25% ） blending in limestone can be used to improve the performance of mixture.
