改性乳化沥青在路面施工中的应用

SBR改性乳化沥青做为高速公路下封层、粘层,是将乳化沥青的应用向前推进了一步。下封层、粘层是沥青路面结构的重要组成部分,改性乳化沥青做沥青路面连接层的胶结材料,使沥青面层抵抗自然因素和车辆荷载弥补了普通沥青的先天性不足。随着工业技术的发展,复合性沥青材料针对路面的功能性要求,对沥青的路用性能不断的改善,使沥青更好服务于现代化的交通需求。从应用的角度,较系统介绍了改性乳化沥青的组成、性能和使用及效果。

The Application of Modified Emulsified Bitumen in the Pavement Construction

The SBR modified emulsified bitumen does for the highway under the sealing course,the tacky surface,was prompted forward the emulsified bitumen application step.The next sealing course,the tacky surface are the bituminous pavement structure important constituent,the modified emulsified bitumen makes the bituminous pavement connection level the cementing material,caused the bituminous pavement resistance natural factor and the vehicles load makes up the ordinary asphalt congenitalness to be insufficient.Along with the industry technology development,the compound bituminous material in view of the road surface function's request,to the asphalt road with the performance unceasing improvement,causes the asphalt to serve well the modernized transportation demand.From the application angle,compared the system to introduce the emulsified bitumen,the modified asphalt,the modified emulsified bitumen composition,the performance and the use and the effect.
