| Outline of Final Research Achievements |
The plate loading test and the light weight deflectometer test are commonly used for evaluating the bearing capacity of the roadbed or base course. However, these survey methods need special apparatus and the interpretation of the result is often difficult. In this study, the newly method for evaluating the bearing capacity of pavement structure based on acceleration caused by loading in ground surface was developed. The impact load was applied at the ground surface by falling iron ball. To perform the test more easily, the acceleration sensor built in the smartphone was utilized. At first, the smartphone application for measuring acceleration was created. Furthermore, the numerical analysis was performed for various pavement structures. As a result, the relationship between elastic modulus and accelerations at the surface of ground was clarified. Using this relationship, the elastic modulus of the roadbed or base course is estimated based on accelerations measured with the smartphone.
