Next-Generation Permeable Pavement for Enhanced Durability and Functionality

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 as compared to dense-graded asphalt mixtures. The most critical shortcomings of permeable pavements include premature durability such as 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 next-generation permeable pavements in Region 6 by optimizing their mechanical, operational, and environmental characteristics. To this end, the objectives of this study are to (i) evaluate the failure mechanisms (e.g., cohesive and adhesive mechanisms) in Open-Graded Friction Course (OGFC) mixtures and the contributions of additives to the mixture durability; (ii) evaluate the effects of Reclaimed Asphalt Pavement (RAP) on the performance and durability of OGFC mixtures; (iii) analyze and quantify bio-remediation processes that may be used to hold and degrade oil and pollutant contaminants into less harmful forms through microbial degradation; (iv) evaluate production, cost, and constructability of OGFC mixtures; and (v) develop an interactive computer tool to facilitate the design of cost-effective and durable OGFC mixtures. These objectives will be achieved through seven research tasks. Task 1 will be led by the University of Arkansas (UARK) with the support of Louisiana State University (LSU) and will include selection of materials and development of the test factorial considering aggregate structure and RAP content, additives, and binder modification, and OGFC mixture types. Task 2 will be led by LSU with the support of UARK and include design and preparation of OGFC mixtures. Task 3 will be led by LSU with the support of UARK and will include evaluation of mechanistic properties and failure mechanisms of OGFC mixtures. Task 4 will be led by LSU and will involve analysis of the bioremediation and microbial degradation of hydrocarbon products. Task 5 will be led by LSU with the support of UARK and will consist of analysis of mixture performance and cost-effectiveness of the OGFC mixtures. Task 6 will be led by UARK with the support of LSU and will involve the development of a computer tool for the design of OGFC mixtures. Task 7 will be led by LSU with the support of UARK and will consist of preparing a final report documenting the findings of this study. Addressing the durability and constructability challenges of OGFC will support its widespread implementation in Region 6. The implementation of durable porous pavements will also reduce the impact of extreme weather events on vulnerable communities and can enhance economic competitiveness and improve living conditions in these communities.
