Abstract: This article takes the shrinkage performance of cement stabilized pellets as the research object. In order to verify the shrinkage performance of cement stabilized pellets more accurately, the characteristics of cement stabilized pellets are first explained, and combined with the temperature shrinkage mechanism, the curing and use Different ages aff ect the primary and secondary status of temperature shrinkage and dry shrinkage strain. Under normal circumstances, the shrinkage strain of cement stabilized aggregate mixture is greater. Therefore, in the construction of the base layer in the frozen soil area, attention should be paid to strengthening quality control and improving its road performance.
