摘　　要：分别以水泥和石灰石粉作为碾压式沥青混凝土的填料,通过测定碾压式沥青混凝土马歇尔稳定度、单轴压缩、小梁弯曲及渗透等性能,对比两种填料对碾压式沥青混凝土上述性能的影响程度。通过研究发现,水泥作为填料时配制的沥青混凝土各项性能均优于石灰岩矿粉作为填料配制的沥青混凝土,它与沥青胶浆形成的"结构沥青"膜厚度略薄,使得"结构沥青"与矿质颗粒之间粘接更加牢固,强度也较高。The cement,limestone powder were used as fillers of rolled asphalt concrete,the performances of Marshall stability,uniaxial compression,trabecular bending and penetration were measured by asphalt concrete in order to investigate the influence degree of the two kinds of fillers on the performances of as-phalt concrete.The research showed that the different performances of asphalt concrete were higher than those of asphalt concrete,when limestone mineral powder were used as fillers.The asphalt liquid cement was used to form formulated asphalt,whose thickness was a little thin,in order to condense formulated as-phalt and mineral particles more firmly,the intensity was higher also.
