【摘要】：在我国高速公路建设迅速发展的同时,高速公路沥青路面早期破坏和耐久性不足问题也一并存在,并已成为影响我国公路健康发展的突出问题。施工质量存在的变异性是造成路面早期破坏的关键因素之一。研究表明,分析与探讨沥青路面原材料、沥青混合料性质与相关变异性、变异性实际控制方案、评价与有效控制沥青路面均匀性,提出沥青路面施工质控管理措施,对沥青路面的施工养护极具重要参考价值。本文以贵州地区的公路沥青路面大量试验及检测数据为基础,对影响沥青路面施工质量且具有变异性的主要技术参数,如沥青的针入度、软化点、延度、集料的级配、粗集料含泥量、针片状颗粒含量、沥青混合料的级配、沥青含量、施工温度以及路面压实度、平整度和厚度进行了研究,分析了其变异性的水平、分布规律及其对路面性能的影响,并提出了减小施工变异性的措施。
[Abstract]:With the rapid development of highway construction in China, the problems of early damage and insufficient durability of highway asphalt pavement also exist, and have become a prominent problem affecting the healthy development of highway in China.The variability of construction quality is one of the key factors that cause the early damage of pavement.The research shows that the raw materials of asphalt pavement, the properties and relative variability of asphalt mixture, the actual control scheme of variability, the evaluation and effective control of asphalt pavement uniformity are analyzed and discussed, and the quality control and management measures for asphalt pavement construction are put forward.It is of great reference value for the construction and maintenance of asphalt pavement.Based on a large number of test and test data of highway asphalt pavement in Guizhou area, this paper deals with the main technical parameters, such as pitch penetration, softening point, ductility, aggregate gradation, which affect the construction quality of asphalt pavement and have variability, such as pitch penetration, softening point, ductility, aggregate gradation, etc.The content of coarse aggregate, needle particle content, gradation of asphalt mixture, asphalt content, construction temperature, compactness, smoothness and thickness of pavement are studied, and the level of variability is analyzed.The distribution law and its influence on pavement performance are put forward, and the measures to reduce the construction variability are put forward.
