| Outline of Final Research Achievements |
This study focuses residual settlement of asphalt pavement system subjected to traffic loads in the view of geotechnical engineering. Firstly, residual deformation properties of the base aggregates during wheel loading were investigated by performing of laboratory wheel loading test. Large residual deformation of the base aggregates due to traffic load was observed in the wheel loading test of asphalt pavement with conventional unreinforced subbase layer. This study also investigated the performance of the followings three geosynthetic-reinforcing technologies applied to the subbase layer on the stability of pavement system; a)geogrid-reinforcing, b)short-fiber mixing and c)combined of short-fiber mixing and geogrid-reinforcing. The residual settlement of the subbase layer caused by traffic loading can be reduced by applied the above reinforcing technologies.
