高速公路采用砂岩碎石铺筑SMA沥青路面试验检测分析

Test and analysis of SMA asphalt pavement with sandstone gravel paving

针对高速公路SMA沥青路面对碎石等原材料要求非常高的特点,在缺乏玄武岩资源时,以本工程实例探讨了因地制宜,就地取材。本文结合湖南省永蓝高速公路沿线砂岩储量丰富,经试验检测分析砂岩满足施工规范指标要求,通过自办砂岩碎石加工场,所产砂岩碎石经检测质量稳定可靠;阐述了从原材料检测、配合比设计试验、现场施工工艺等方面的质量控制,确保应用砂岩碎石SMA沥青路面铺筑品质,沥青路面工程通过交工验收质量检测满足施工规范技术要求。

In view of the highway asphalt pavement SMA characteristics of gravel and other raw materials is very high, in the absence of basalt resource, with the engineering examples of the local conditions, local materials. According to Hunan Province Yongzhou Lanshan expressway along the sandstone is abundant, the test specification to meet the construction requirements analysis of sandstone, sandstone through self processing, producing sandstone after testing quality is stable and reliable; expounds with raw materials inspection and control design than the quality test and construction process, to ensure the application of sandstone SMA gravel asphalt pavement paving asphalt pavement engineering quality, through the inspection and acceptance of quality inspection to meet the requirements of construction technical specification.
