通过试验和数理统计方法,研究了基于层位分工论的沥青混凝土路面材料配合比设计管理方法和沥青混凝土路面施工质量简易动态管理方法。研究结果表明:根据层位分工论和贝雷法,可以确定沥青混凝土路面上、中、下面层贝雷法级配参数CA比、FAC比、粗集料设计密度的合理取值,同时可以确定沥青混凝土路面上、中、下面层的配合比性能检验指标合理取值,将这些合理取值的研究成果应用于工程实践中,可以有效提高半刚性基层沥青混凝土路面的结构性使用性能;通过监测每旬内路面工程各项检测技术指标的每旬标准差S和变异系数CV等数理统计指标的变化情况,可以采取相应工程措施进行改进,确保沥青混凝土路面施工质量始终保持在一个较高水平。
Through experimental and mathematical statistics methods, the design method of mix proportion of asphalt concrete pavement based on layer division theory and simple and dynamic management method of asphalt pavement construction quality are studied. The results show that according to the division of labor theory and Berets method, it is possible to determine the rational values of the Bereth gradation parameter CA ratio, FAC ratio and coarse aggregate design density in the upper, middle and lower asphalt pavement, meanwhile, it can be determined Asphalt concrete pavement, the middle and lower layers with the ratio of the performance test indicators reasonable value, these reasonable values of the research results used in engineering practice, can effectively improve the semi-rigid base asphalt concrete pavement structural performance; through monitoring Every ten-day pavement standard engineering standards of the ten-day standard deviation S and coefficient of variation CV mathematical statistics such as changes in the situation, you can take appropriate engineering measures to be improved to ensure that asphalt pavement construction quality has remained at a high level.
