结合高速公路水泥混凝土桥面沥青混凝土铺装实体工程,对桥面板应用露石混凝土技术,包括露石混凝土配合比设计、路用性能以及施工技术等进行了研究。结果表明:露石技术应用于水泥混凝土桥面板,可以有效提高层间过渡区的抗剪强度,不会对层间过渡区的黏结强度产生不利影响,可以有效提高水泥混凝土桥面沥青混凝土铺装结构的稳定性,减小铺装层推移和拥包病害。
Based on the concrete construction of asphalt concrete pavement of expressway cement concrete bridge deck, the dewstone concrete technology, including the design of mix of exposed stone concrete, road performance and construction technology, was studied. The results show that the dewstone technology can be applied to the concrete bridge deck, which can effectively improve the shear strength of the interlayer transition zone without adversely affecting the bond strength of the interlayer transition zone, and can effectively improve the asphalt concrete pavement The stability of the structure, reducing pavement layering and bagging disease.
