1 cm微罩面施工技术在高速公路修复养护中应用研究OA
Research on the Application of 1 cm Microcover Construction Technology in Highway Repair and Maintenance
结合实际施工项目,对河北省唐山市G0121京秦高速公路 K98+680-K151+208出现的横缝、纵缝、龟裂、细小裸缝、疲劳裂缝等面层病害状况和1cm特种改性沥青胶结料微罩面施工工艺流程、质量控制要点、主要材料技术指标等进行统计分析,对1cm微罩面材料要求、配合比设计、铣刨、吹扫、粘层油洒布、混合料拌合、运输、摊铺、压实、开放交通等施工技术要点进行总结.旨在推广1cm特种改性沥青胶结料微罩面施工工艺在高速公路修复养护中的应用,提高路面损坏状况指数PCI指标,进一步改善路面技术状况指数PQI指标,为我国高速公路养护工程路面修复施工提供施工参考和技术依据.
Combined with the actual construction project,this paper makes a statistical analysis on the surface diseases of K98+680-K151+208 of G0121 Beijing-Qinhuangdao Expressway in Tangshan City,Hebei Province,such as transverse cracks,longitudinal cracks,mapping cracks,small bare cracks and fa-tigue cracks,as well as the construction process,quality control points and main material technical indica-tors of 1 cm special modified asphalt binder micro-surface.The main technical points of 1 cm micro-surface material requirements,mix ratio design,milling,purging,viscous oil spreading,mixing,transportation,spreading,compaction,open traffic are summarized.The aim is to promote the application of 1cm special modified asphalt cement micro-cladding construction technology in highway repair and maintenance,im-prove the pavement damage index PCI index,further improve the pavement technical condition index PQI index,and provide construction reference and technical basis for the pavement repair construction of high-way maintenance engineering in China.
