| Abstract: | In this paper, the equations to calculate strains in pavement structures with surface deflection basin are developed. The Falling Weight Deflectometer measurements of some stretches in Shanghai were used to evaluate the conditions of structural strain and bearing capacity. The results indicate that it has good precision for using in practice and has the characteristics of fast and nondestruction. |
