SASW used in quality assurance for performance of highway subgrade |
| |
| Abstract: | The spectral analysis of surface waves system on site testing for performance of highways subgrade is discussed in this paper. On the basis of the modulus of resilience tested on site, the mechanical performance of highways subgrade was investigated in a systematical way by the Rayleigh Wave test, bending test, field CBR and loading plate test. Using statistics, an empirical relation between Rayleigh Wave velocity and modulus of resilience for highways subgrades is established, and the validity of the subgrade modulus of resilience calculated from the bending test is verified. The test methods and the assurance of the subgrade mechanical characteristics are proposed. |
