Optimization method for grading of rubber particles in rubber cement stabilized macadam mixture
The invention relates to an optimization method for grading of rubber particles in a rubber cement stabilized macadam mixture. The optimization method comprises the following steps: step 1, accurately controlling the grading of aggregates; step 2, determining the uniform mixing amount of rubber and the uniform mixing amount of cement; step 3, selecting six gears with the maximum particle size in the size fraction below 9.5 mm as replacement gears, and correspondingly manufacturing rubber particles of the same gears; step 4, performing same-volume replacement on the aggregate gears with the particle sizes of more than 2.36 mm by adopting the same-gear rubber particles, and performing rubber particle gradation on the aggregate gears with the particle sizes of less than 2.36 by adopting a downshift half-folding method to obtain six groups of rubber particle gradation schemes; step 5, preparing a common cement stabilized macadam test piece and a rubber cement stabilized macadam test piece under six grading schemes; step 6, comparing to obtain an optimal grading scheme; according to the method, the optimal rubber particle replacement scheme can be determined, and the research of doping the rubber particles in the ordinary cement stabilized macadam can be promoted.
本发明涉及一种橡胶水泥稳定碎石混合料中橡胶颗粒级配的优化方法，包括以下步骤：步骤1、精确控制集料的级配；步骤2、确定橡胶统一掺量和水泥统一掺量：步骤3、选取9.5mm以下粒级中粒径尺寸最大的六个档位作为替换档位，对应制作相同档位的橡胶颗粒；步骤4、对于粒径2.36mm以上的集料档位采用同档位的橡胶颗粒同体积替换，对于粒径2.36以下的集料档位采用降档折半法进行橡胶颗粒级配，得到六组橡胶颗粒级配方案；步骤5、制备普通水泥稳定碎石试件和六种级配方案下的橡胶水泥稳定碎石试件；步骤6、比较得到最佳的级配方案；本发明可实现最佳的橡胶颗粒替换方案的确定，有助于促进普通水泥稳定碎石中掺杂橡胶颗粒的研究。
