Passenger car tire recycling is more difficult than truck tires; and when adding crumb rubber into asphalt, it is easy to have poor storage stability problem due to the difference in the specific gravity of the two materials. Problems such as poor storage stability. In this study, we explores the difference between the rubber asphalt made of truck tire crumb rubber and passenger car tire crumb rubber, and whether the excessive fiber contained in the crumb rubber affect the asphalt properties, and uses finer particles of crumb rubber and silane coupling agent to evaluate its storage stability and physical properties. The results show that the physical properties of rubber asphalt made from passenger car tire crumb rubber are slightly inferior to truck tire crumb rubber, but the difference is not significant, both can be made into rubber asphalt that meets the specifications. And if the crumb rubber contains fiber, the asphalt properties are improved. As for the storage stability, the use of finer particles of rubber can be significantly improved, but adding silane coupling agent failed to produce the expected results in this study. It may be that the method of use or the corresponding materials used are still to be further studied.
