Abstract
This paper mainly studies the effects of different cement content (5%, 7%, 9%, 11%, 13%, 15%) on the unconfined compressive strength of cement stabilized macadam base materials. The effects of different cement content on the compressive properties of the mixture were compared by unconfined compressive strength test analysis. The results show that the influence of cement content on the early strength of the road base layer is greater than the impact on the later strength. When the age is 1 day, the cement content increases from 9% to 11%, and the unconfined compressive strength increase rate of the test piece is the largest (35.93%).
