摘要
成品橡胶沥青作为一种新型路面材料,具有优良的高温稳定性、抗疲劳和降噪特性。文章在分析桥面沥青铺装体系共性特点和贵州省当地桥面使用特性的基础上,首次在贵州应用成品橡胶沥青桥面铺装结构,并进行了成品橡胶沥青SMA13级配设计、性能验证及橡胶沥青桥面铺装施工工艺优化。
As a new pavement materials, terminal blended asphalt-rubber is proved with excellent high temperature stability, resistance to fatigue and noise reduction. Based on the analysis of the common characteristics of asphalt bridge pavement system and personality characteristics of bridge deck pavement in Guizhou province, terminal blended asphalt-rubber pavement structure is first put forward in Guizhou province. The grading design, performance verification of terminal blended asphalt-rubber SMA-13 is analyzed, and the construction technology of deck pavement is optimized.
