Preparation method of normal-temperature mixing type emulsified asphalt mixture
The invention provides a preparation method of a normal-temperature mixing type emulsified asphalt mixture. The preparation method comprises the specific steps of S1, determining an engineering design grading range according to sieve pores and the type of the asphalt mixture; S2, selecting raw materials; S3, designing the grading; S4, determining the optimal water content, specifically, determining the optimal water content through a corrected soil test; S5, forming and curing, specifically, mixing the raw materials of each grading, compacting the double surfaces for 50 times respectively, curing for 2 days in a mold at the temperature of 90 DEG C, then compacting the double surfaces for 25 times respectively, standing for 24 hours at the temperature of 20 +/-5 DEG C, and demolding; S6, determining the optimal emulsified asphalt amount; S7, conducting performance detection, specifically, measuring the gross volume relative density, the maximum theoretical relative density, the splitting strength and the void ratio; and S8, when all the performance indexes meet the requirements, completing the mix proportion design, and if the performance indexes do not meet the requirements, redesigning the mixture from the step S2, and repeating the steps from the step S2 to the step S7. The method has good economic benefits, environmental protection benefits and social benefits.
本发明提出了一种常温拌和型乳化沥青混合料制备方法，具体步骤如下：S1、根据筛孔以及沥青混合料类型确定工程设计级配范围；S2、选择原材料；S3、设计级配；S4、确定最佳含水率：通过修正土工试验，确定最佳含水率；S5、成型和养生：各级配原材料拌和，双面各击实50次后,模内90℃养生2天后立即双面各击实25次，20±5℃下静置24h脱模；S6：确定最佳乳化沥青用量；S7、检测性能：测定毛体积相对密度、最大理论相对密度、劈裂强度、空隙率；S8、性能指标全部满足要求时，则完成配合比设计，如果性能指标不满足要求，则从S2开始，重新设计混合料，重复S2至S7。本发明具有良好的经济效益、环保效益和社会效益。
