The Influence of porous asphalt pavement based on DEMATEL

摘要

Taiwan position is in the subtropics, the climate is high temperature and much rains of year. Freeway mostly uses traditional dense grade in pavement construction, so the pavement could not remove water quickly in rainy day. It will deteriorate by rutting and aging, due to increasing maintenance frequency and cost. Porous asphalt pavement has high performance on road user safe and amenity in many countries. But the prescription in porous asphalt is Variable, for example, the fiber has miner and wood. Base on multiple conditions, the best performance can choice by multiple criteria decision method. This methodology needs the criteria under independent, but the real world is not. The study use Decision-Making Trial and Evaluation Laboratory method to establish the relationship in criteria. With result, the drainage capacity was the important factor in porous asphalt pavement.
