高速公路ATB-30粗粒式沥青碎石上基层施工技术研究

Study on Construction Technology of ATB-30 Coarse-Grained Asphalt Gravel Upper Base on Highway

为研究高速公路ATB-30粗粒式沥青碎石上基层施工技术及应用,提高高速公路基层施工质量,论文结合实际工程,详细阐述了ATB-30粗粒式沥青碎石上基层各原材料的技术指标,重点研究了ATB-30粗粒式沥青碎石上基层施工技术要点,并通过钻芯取样的方式进行施工质量检测。检测结果表明,该项目的 ATB-30粗粒式沥青碎石上基层施工质量整体良好,厚度和外观均满足规范要求。

In order to improve the construction quality of expressway ATB-30 coarse-grained asphalt gravel base construction technology and its application, combined with the actual project, this paper elaborates the technical index of each raw material of ATB-30coarse-grained asphalt gravel base, focuses on the construction technical points of ATB-30 coarse-grained asphalt gravel base, and carries out construction quality inspection through the way of core sampling. The test results show that the construction quality of the ATB-30coarse-grained asphalt gravel base of the project is good, and the thickness and appearance meet the requirements of the code.
