Project Description: The South-Central region of the United States, which is characterized by heavy rainfall conditions and shallow groundwater table, may significantly benefit from the widescale implementation of porous asphalt, especially if similar performance to regular dense-graded asphalt mixtures can be achieved. Yet, there have been some difficulties using porous asphalt as a wearing surface course, largely because of its lower durability when compared to dense-graded asphalt mixtures. The most critical shortcomings of permeable pavement include premature durability problems (raveling and stripping), and clogging of voids by dirt, which result in shorter service life and higher costs. 

The goal of this study is to enhance the use of a next-generation permeable pavement in Region 6 by optimizing its mechanical, operational, and environmental characteristics.
