某高速公路扩容工程试验段沥青路面施工方案研究

Research on Construction Scheme of Asphalt Pavement in the Test Section of an Expressway Expansion Project

文章基于某高速公路扩容工程的沥青混凝土面层试验段施工,研究和探讨影响沥青路面施工的关键因素,首先分析沥青路面原材料及配合比,结合各项性能指标进行相关试验,以期满足设计及规范的要求,然后研究试验段施工方案,具体分析测量放样、混合料拌和与运输、路面摊铺等施工要点,以试验确定出最优施工方案。该试验段施工取得了较为理想的施工效果,为今后沥青混凝料面层大面积施工积累了宝贵的施工经验。

Based on the construction of asphalt concrete pavement test section of an expressway expansion project,this paper studies and discusses key factors affecting the construction of asphalt pavement.Firstly,the raw materials and mix ratio of asphalt pavement are analyzed,and the relevant tests are carried out in combination with various performance indicators in order to meet the requirements of the design and specification.Then,the construction scheme of the test section is studied,and the construction points such as measurement and lofting,mixture mixing and transportation,pavement paving are analyzed in detail,and the optimal construction scheme is determined by test.The construction of the test section has achieved ideal construction results,which has accumulated valuable construction experience for the large-scale construction of asphalt concrete pavement in the future.
