【 摘 要 】

At present, there is no test method specification for the optimum emulsified asphalt dosage of cold-mixed asphalt mixture. The current specifications are mainly for hot mix asphalt and cold recycled asphalt mixture. Based on the previous studies, this paper initially selected the AC-13 group as the best grading, discussed the mixing and health environment during the cold-mixed asphalt mixture test piece forming, the optimum emulsified asphalt dosage for the AC-13 cold-mixed asphalt mixture is determined by the Marshall test and the water-immersed Marshall test, it was verified by dry and wet splitting test and high temperature rutting test. The results show that the application of the Marshall test and the water-immersed Marshall test can determine the optimum amount of emulsified asphalt for cold-mixed asphalt mixture. It can provide reference for the determination of the best emulsified asphalt dosage for cold-mixed emulsified asphalt mixture.
