In order to guide the test of mineral emulsified asphalt fog seal coating and improve the engineering quality of the seal coat, according to the characteristics and application requirements of the mineral emulsified asphalt fog seal coating, a variety of detection methods were used to test the raw material of emulsified asphalt mineral slurry, emulsified asphalt mineral slurry and its mixture, and the specific technical requirements were determined according to the test results. In the test, the performance evaluation method of emulsified asphalt mineral slurry was studied. Five kinds of emulsified asphalt mineral slurry with different raw materials composition were prepared. Then nine properties of emulsified asphalt mineral slurry, including stoker viscosity, 80℃ heat resistance, adhesion, artificial accelerated aging and Volatile Organic Compounds (VOC) content, were tested from four aspects of physical performance, workability, durability and environmental protection. Finally, the performance and technical requirements were determined. In addition, the requirements of aging resistance and environmental protection such as no obvious change of artificial accelerated aging for 250h and VOC content no more than 120g/L were put forward for the first time.
