摘　　要：压实度与空隙率的变异性影响着沥青路面的路用性能。本文结合某高速公路工程实际,开展沥青路面压实度与空隙率变异性的分析研究,根据工程实测数据,分析了影响压实度与空隙率变异的主要因素以及两者之间的相关性,进而提出减小压实度和空隙率变异性的施工控制措施,以期减小和控制面层的施工参数变异性。The variability of compactness and crevice rate influence the asphalt pavement performance. Combined with the expressway practice, this paper studies compactness and crevice rate variability and analyzed the main influence factors of compactness and crevice rate variability according to the project test data. Then the relationship between the compactness variability and the crevice rate variability are analyzed. At last this paper proposed the construction control measures of reducing compactness and crevice rate variability.
