摘要
提出了茂名ＡＨ—７０沥青用聚乙烯改性制备沥青碎石玛蹄脂ＳＭＡ。试验结果表明沥青和ＳＭＡ的材料性质、力学强度、热稳性、水稳性和抗车辙性能良好，达到高标准的路面技术要求，能满足南方湿热区修建高等级道路工程的需要。
The stone Mastic Asphalt adding the polyethylene modified native bitumen has been presented As the results of laboratory tests,it is a fact that the material not only agrees with the technical criterion of high grade bitumen and meets the specification of stone Mastic Asphalt,but also behaves good property such as higher mechanical strength,higher water stability and ability to resist high temperature rutting It is satisfied with the high grade road construction for the wet-heat weather region in south China
