PR改性沥青混合料设计及施工质量控制探讨

Discussion on PR modified asphalt mixture design and construction quality control

结合忻阜高速公路工程施工实践,介绍了PR改性沥青混合料的原材料要求和配合比设计,并对PR改性沥青混合料的拌合、运输、摊铺、碾压等施工工艺作了具体阐述,指出PR改性沥青混合料能有效降低沥青路面车辙病害,值得推广。

Combining with Xin-Fu highway engineering construction practice, this article introduces the raw material requirements and mixing ratio design of PR modified asphalt mixture, and specificially expounds construction technology of PR modified asphalt mixture including mixing, transportation, paving, and rolling, and then points out that： PR modified asphalt mixture can effectively reduce asphalt pavement wheel rutting diseases and is worth promoting.
