摘　　要：基于人行及非机动车道的结构特点及使用特征,结合浇注式沥青铺装方案在我国长大桥梁钢桥面铺装中取得的良好应用效果,从沥青混合料设计指标、原材料性能、混合料性能和实体工程验证等方面开展直馏沥青浇注式铺装在人行及非机动车道上的应用研究。研究结果表明:15#直馏硬质沥青具有更高闪点与软化点,对浇注式沥青混合料具有更好的适用性,且直馏浇注式沥青混合料具有良好的高低温稳定性,可满足人行及非机动车道铺装层的性能要求。研究成果可为类似人行及非机动车道钢桥面铺装方案设计提供参考。Based on the structural characteristics and usage characteristics of pedestrian and non motorized lanes,combined with the good application effect of guss asphalt pavement scheme in the steel deck pavement of long span bridges in China,the application research of straight run guss asphalt pavement on pedestrian and non motorized lanes is carried out from the as-pects of asphalt mixture design indicators,raw material performance,mixture performance,and physical engineering verifica-tion.The research results indicate that 15#straight run hard asphalt has a higher flash point and softening point,which makes it more suitable for guss asphalt mixtures.The guss asphalt mixture with straight run asphalt has good high and low temperature stability and can meet the performance requirements of pedestrian and non motorized lane pavement.The re-search results can provide reference for the design of similar pedestrian and non motorized lanes steel bridge deck pavement schemes.
