钢桥面环氧沥青浇筑式混凝土铺装路用性能研究

Research on pavement performance of steel deck epoxy asphalt pouring concrete

通过不同结合料含量流动性检测选取了适宜的结合料用量,并确定了10%结合料用量条件下混合料适宜的拌和时间,高低温试验结果表明,环氧沥青浇筑式沥青混合料的低温性能优于普通碾压式环氧沥青混凝土,且其低温性能受拌和时间影响不大,与普通改性沥青相比,环氧沥青能够显著改善浇筑式沥青混合料的高温稳定性。

Through different binder contents flow detection selected suitable binder contents, and identified the suitable mixing time of mixture under the conditions of 10% binder content, the high and low temperature experiment results showed that, the low temperature performance of epoxy asphalt pouring asphalt mixture better than ordinary roller type epoxy asphalt concrete, and its low temperature properties little effect by mixing time, compared with common modified asphalt, epoxy asphalt could significantly improve the high temperature stability of pouring asphalt mixture.
