Abstract
In order to study the road performance of the graded-gravel material, the dynamic and static rebound modulus test of continuous-graded gravel was carried out, and through the tested road for field rebound modulus test and reverse, while the indoor and field CBR was tested. The results show that with the change of the load on the graded-gravel material, the modulus shows a good non-linear characteristic, and the modulus gradually increases with the load increasing. The indoor and field rebound modulus of the graded-gravel mixes are in accordance with the current specification requirements, and the CBR test value also meets the specification requirements. The research has reference significance for understanding the road performance characteristics of the graded-gravel and the future design and construction.
