| Research Abstract |
The key components of the this research are development of (1) a measuring tire ? pavement contact stress measuring system, (2) the static and dynamic structural analysis of pavement, and (3) a new method of diagnosis necessary for the maintenance of pavement. Regarding (1), sensors for contact stress measurement were newly developed and mounted on a force plate. It is found that contact stresses in three directions are more accurately measured. Regarding (2), theoretical solution pavement structure subjected to impulse force is derived. By using the solution, wave propagation of displacements and stresses can be more accurately predicted. Finally regarding (3), FWD testing device became popular as the nondestructive testing of the pavement structure. Layer moduli and damping coefficients can be estimated more accurately from measured surface deflections by using wave propagation solution.
