随着国家经济的快速发展,为适应公路建设发展的需要,在使沥青路面满足使用要求、保证路面质量的同时,对公路行车舒适性的要求也越来越高。平整度反映了公路通车后路面的整体效果,体现了公路的使用品质,是行车环境舒适性的一个重要指标。本文主要从基层、集料的规格和质量、混合料施工(包括拌和、运输、摊铺和碾压等)及接缝处理等方面对提高沥青路面平整度的措施进行分析,以指导工程实践。
With the rapid development of the national economy, in order to meet the needs of the development of highway construction, the asphalt pavement meets the requirements of use and the quality of the pavement is ensured. Meanwhile, the demands on road traffic comfort are also getting higher and higher. The flatness reflects the overall effect of the road surface after the road opened to traffic and reflects the quality of use of the road, which is an important indicator of the comfort of driving environment. In this paper, the measures to improve the evenness of asphalt pavement are analyzed in terms of grass-roots, the specifications and quality of aggregate, the construction of mixture (including mixing, transportation, paving and rolling, etc.) and seams.
