摘　　要：消石灰通常以替代矿粉的形式加入到沥青混合料中来提供混合料的抗剥落性能 ,文中对消石灰替代矿粉的最佳替代量进行了研究 ,结果表明从水稳定性角度来看消石灰替代矿粉的合适比例为 16 .7% (即消石灰占矿料总重量的 1% )时的抗剥落性能较好。同时对掺加消石灰的沥青混合料的路用性能进行了试验研究 ,结果表明掺加消石灰后沥青混合料的低温抗裂性、高温稳定性和疲劳性能都有不同程度的提高和改善。Hydrated lime as anti stripping is added to mixture to substituting for filler, the optimal content of hydrated lime substituted for filler is studied in this paper, the results suggest that from water stability the optimum content of substitute is 16 7%, that is 1% by weight of total aggregate At the same time the performances of mixture added hydrated lime are tested, the results show the mixture added hydrated lime can promote or meliorate its low temperature anti crack performance, high temperature stability and anti fatigue performance
