Abstract
In Japan, innovations leading to lower maintenance and repair costs for asphalt pavement structures are required. For a general roadway in Japan, it is only possible to apply a soil reinforcing technology that is equivalent to excavating and backfilling concerned with maintenance of lifeline facilities. In this study, therefore, model loading tests on asphalt pavement with fiber-reinforced recycled concrete aggregate layer were performed to develop a new soil reinforcing technique that can be applied to ordinary road. As the results of the present study, it was confirmed that mixing short fiber in the subbase layer made of crushed concrete aggregate has advantage to reducing the residual settlement caused by heavy traffic load.
