In terms of longer hardening time of emulsified asphalt seal mixture, a rapid hardening seal mixture was prepared by adding cement and carbon fibre to the Styrene–Butadiene-Rubber (SBR)-modified emulsified asphalt. The mix proportion of mixture was determined by testing the mixable time, consistency, wet track abrasion value, adhered sand content, cohesion force and the cracking rate. The microscopic mechanisms of rapid hardening and cracking control were studied using the Scanning Electron Microscopy (SEM) and the Fourier Transform Infrared Spectroscopy (FTIR). It is found that the optimum contents of SBR-modified emulsified asphalt, added water, cement and carbon fibre in the prepared mixture are 12%, 13%, 4% and 4%, respectively. At 20°C, with a relative humidity of 90% and a wind speed of 10 km/h, the opening time to traffic of mixture adding 4% ordinary Portland cement can be 2 h earlier than that without cement.

针对乳化沥青封闭混合料硬化时间较长的问题，在苯乙烯-丁二烯-橡胶（SBR）改性乳化沥青中加入水泥和碳纤维制备了一种快速硬化封闭混合料。通过测试混合时间、稠度、湿道磨损值、附着砂含量、内聚力和开裂率来确定混合料的混合比例。使用扫描电子显微镜 (SEM) 和傅立叶变换红外光谱 (FTIR) 研究了快速硬化和裂纹控制的微观机制。发现所制备的混合料中SBR改性乳化沥青、加水、水泥和碳纤维的最佳含量分别为12%、13%、4%和4%。在 20°C，相对湿度为 90%，风速为 10 公里/小时，
