【摘要】：为适应交通事业迅速发展的需要，我国公路工程建设中不断研究推广新材料、新工艺。其中ATB-30密级配沥青稳定碎石也被推广应用在高速公路和市政道路中。国道112线高速公路路面工程是采用12cm厚的ATB-30沥青稳定碎石混合料做为下面层，这在天津地区还属首次。本篇论文通过对现场试验、施工、检测等方面的跟踪研究，形成了一整套对应于大粒径沥青稳定碎石一次性摊铺施工工艺的技术方法。内容涵盖原材料控制、配合比试验、混合料拌和、混合料运输、现场摊铺、碾压等。通过理论分析、试验检测、施工过程检测等手段，找出施工时所需要解决的一系列问题，，并找出了应对的技术措施。 本论文所得出的各种施工方法，都根据大粒径沥青混合料的特点，从现场的实际操作出发，对今后类似工程的施工具有很好的借鉴作用。
[Abstract]:In order to meet the needs of the rapid development of transportation industry, new materials and techniques have been continuously studied and popularized in highway engineering construction in China. Among them, ATB-30 dense gradation asphalt stabilized macadam is also widely used in highway and municipal road. The pavement engineering of National Highway 112 used ATB-30 asphalt stabilized macadam mixture with 12cm thickness as the lower layer, which is the first time in Tianjin. Based on the field test, construction and inspection, a set of technical methods corresponding to the one-off paving process of large-size asphalt stabilized macadam are formed. The content covers raw material control, mix test, mixture mixing, mixture transportation, site spreading, rolling, etc. By means of theoretical analysis, test and construction process test, a series of problems needed to be solved in construction are found out, and the corresponding technical measures are found out. According to the characteristics of large particle size asphalt mixture and the actual operation on the spot, the various construction methods obtained in this paper can be used for reference in the construction of similar projects in the future.
