介绍了新修订的《公路水泥混凝土路面施工技术规范》JTGF30—2011中的隔离封层与缓冲封层设置技术,它是长寿命水泥混凝土路面整体结构优化的重要内容之一。在水泥混凝土路面板底半刚性基层上设置热沥青石屑或3种薄膜隔离封层;在贫混凝土等刚性基层上设置沥青混凝土或油毡局部缓冲封层。期望实现刚性面板的软着陆,从而切实延长水泥混凝土路面的实际使用寿命。
This article introduces the installation technology of isolation seal and buffer seal in the newly revised JTGF30-2011 “Technical Specifications for Construction of Highway Cement Concrete Pavement”. It is one of the important contents of the overall structure optimization of long-life cement concrete pavement. On the semi-rigid base of the cement concrete pavement, hot asphalt or three kinds of thin film isolation sealings are set on the semi-rigid base of cement concrete pavement; and the local cushioning seal of asphalt concrete or linoleum is set on the rigid base such as lean concrete. Expected to achieve a soft landing of rigid panels, so as to effectively extend the actual service life of cement concrete pavement.
