摘　　要：分别采取水泥替代矿粉作为填料以及在沥青中混入钛酸酯偶联剂两种措施进行试验研究,旨在改善其水稳定性能,试验结果表明,采用水泥替代矿粉作为填料后,掺加抗车辙剂的沥青混合料的冻融劈裂强度比有很大提高,而在沥青中混入钛酸酯偶联剂作为界面改性剂的做法不甚理想。This paper has an experiment and research of two measures on adopting the cement to be filling instead of mineral powder and dropping the titanate coupling agent in asphalt. It aims at improving the water stability. The research results demonstrate that after adopting the cement to be fining instead of mineral powder, the asphalt mixtures＇s freeze-thaw split strenghth ratio improve by adulterating anti-rut agent, but the method of dropping the titanate coupling agent as interracial modifer at asphalt mixture is nonideal.
