“白+白”水泥混凝土路面施工工艺

Construction Technology of “White+White”Cement Concrete Pavement

为了保护环境,减少天然河砂的采挖和使用,文章提出水泥混凝土路面下层采用机制砂混凝土、上层采用天然砂混凝土的复合一体式水泥路面("白+白"整体式水泥混凝土路面)设计,并结合工程实例,介绍了"白+白"整体式水泥混凝土路面的施工工艺及其社会效益和经济效益,可为"白+白"整体式水泥混凝土路面的推广应用提供参考。

In order to protect the environment and reduce the dredging and use of natural river sand,this article proposed the composite monolithic cement pavement（＂White＋ White＂monolithic cement con-crete pavement）design of using the manufactured-sand concrete for the underlying layer of cement concrete pavement and using the natural sand concrete for upper layer,then in combination with engineering example,it introduced the construction technology of＂white＋white＂monolithic cement concrete pavement as well as its social and economic benefits,which can provide the reference for the promo-tion and application of＂white＋white＂monolithic cement concrete pavement.
