| Abstract: | Based on the online real-time detection during the course of subgrade compaction, relationship between modulus of resilience and degree of compaction, dynamic stiffness and degree of compaction, as well as modulus of resilience and dynamic stiffness was studied by taking project of Class A Highway from Baotou to Guyangmingdeng as an example. Results showed a linear relationship between the modulus of resilience of subgrade and dynamic stiffness of the soil tested in the course of compaction, verifying the feasibility of detecting modulus of resilience with online real-time detection technology. |
