江西省的高速公路建设本阶段以山区为主,山区高速公路桥隧比例高,如何防止桥梁、隧道沥青混凝土路面出现早期病害,是建设者首先应该考虑的问题。桥梁部分沥青混凝土施工的质量控制除了要加强沥青混凝土路面的施工质量控制外,还要着重处理好桥面的防水层施工质量,文章就高速公路桥面防水层结构型式:8mmSBS改性沥青下封层(同步封层车洒布施工)施工工艺、施工质量控制进行一些探讨。
In this stage, the expressway construction in Jiangxi Province is dominated by mountainous areas, and there is a high proportion of bridges and tunnels in mountainous expressways. How to prevent early disease of asphalt concrete pavement of bridges and tunnels is the first question for builders. In addition to strengthening the construction quality control of asphalt concrete pavement, the quality control of bridge asphalt pavement construction should also focus on the construction quality of the waterproof layer of the bridge deck. The article is about the structure type of the bridge deck waterproofing layer of the bridge: 8mmSBS modified asphalt under seal Layer (synchronous seal car shed cloth construction) construction technology, construction quality control to conduct some discussions.
