摘　　要：采用水泥和消石灰代替部分矿粉的措施提高沥青混合料的水稳定性,研究了二者与沥青混合料最佳油石比的关系,并确定了最佳掺量。结果表明,水泥和消石灰对沥青混合料的水稳定性能均有明显的提高,且随着掺量的增加抗水损害能力呈现先增大后减小的趋势。The measure to improve the water stability of asphalt mixture using cement and hydrated lime to replace part of the mineral powder is adopted, and the optima asphalt - aggregate - ratio of cement and hydrated lime and asphalt is ascertained. The result shows that the cement and hydrated lime has improved the water stability of the asphalt mixture obviously, and the anti - moisture damage ability decreased with the increase of cement and hydrated lime content.
