市政道路改建中桥梁伸缩缝沥青路面平整度施工技术应用研究

Research on the Application of Bridge Expansion Joint Asphalt Pavement Flatness Construction Technology in Municipal Road Reconstruction

在路面平整度施工过程中,受桥梁伸缩缝结构特殊性的影响,路面平整度较低,为此,文章选择基质沥青材料和集料的性能指标参数,按照横向伸缩缝和纵向伸缩缝采取了针对性的施工措施。测试结果显示,施工路面的IRI最大值达到了1.67,最小值达到了1.32,平整度水平较高。

In the process of pavement flatness construction,the pavement flatness is low due to the particularity of bridge expansion joint structure.In this regard,the performance index parameters of matrix asphalt materials and aggregates are selected,and targeted construction measures are adopted according to the transverse expansion joint and longitudinal expansion joint.The test results show that the maximum IRI of the construction pavement reaches 1.67,and the minimum value reaches 1.32,indicating a high level of flatness.
