Influence of Molding Process on the Performance of Sisal Fiber Cement–Emulsified Asphalt Mixture

In order to explore the influence of the molding process on the performance of sisal fiber cement–emulsified asphalt mixture, specimens were formed by different molding processes. Different mixing methods, mixing times, and secondary compaction times were used. The effects of the different molding processes on the performance of sisal fiber cement–emulsified asphalt mixtures were investigated by low-temperature splitting test, high-temperature stability test, water stability test, water seepage test, and four-point bending test. In this paper, the gray correlation theory is used to analyze the correlation between different molding processes and the performance of the mixtures. The results show that the best mixing method to adopt is of adding aggregate and sisal fiber first, then water, then cement, and finally adding emulsified asphalt. The mixing times for the addition of aggregate and sisal fiber is 30 s, then adding water for 30 s, then adding cement for 90 s, and then adding emulsified asphalt for 90 s. The time of secondary compaction after the first compaction for 15 min is most conducive to the performance of sisal fiber cement–emulsified asphalt mixture.
