Study on the Recycling Method for Drainage Asphalt Pavement and Evaluation for its Durability

Abstract:

In Japan, drainage asphalt pavement (DAP) is widely used especially on the highway and the express way. However, because of the existing porous asphalt materials consist of DAP use polymer modified bitumen, and the aggregate gradation of DAP is differ from conventional mixture, it is difficult to use those porous asphalt materials as the recycled aggregate for reclaimed asphalt pavement. Therefore, the recycling method for recycled DAP which were consisted of recycled porous asphalt materials and virgin aggregates has not been established yet. This paper describes that the recycling method for recycled DAP was considered, and the workability and five years durability was also verified by trial construction of the recycle DAP and new DAP which were consisted of virgin aggregate on the national highway.
