西江公路铁路两用大桥铺装层维修技术与成本分析

Maintenance Technologies and Cost Analysis for Paving Layer of Xi jiang Guangdong HighwayRailway Doublelevel Bridge

采用SBS改性沥青、沥青纤维砼、分隔式沥青砼底层等不同的沥青混凝土结构层;采用沥青砂浆、土工膜、改性环氧脂粘贴玻璃隔栅防水层等结构,进行西江大桥的维修试验,通过试验的技术、成本分析与比较。

In this study,different structural layers,such as SBSmodified asphalt,fibrous asphalt concrete and separated asphalt concrete layer,and different waterproof layers,such as asphalt mortar,civil construction coating and glass grilles glued by modififed epoxy resin,are adopted to conduct maintenance experiments of 3 plans.The optimum way is finally obtained for the maintenance of paving layer of the bridge through experimental technology,cost analysis and comparison.
