| Abstract |
An extensive effort is actively being made to implement permeable pavement systems in urban or residential areas of South Korea in order to achieve efficient water circulation system based on low impact development (LID) design concept. This study aims to establish the design factors and procedure for permeable asphalt pavements structural design. Based on the review of previous studies, the 1993 AASHTO design method is found to be adequate for permeable pavements structural design. In this study, the design program based on 1993 AASHTO design procedure in conjunction with domestic roadway design standards was developed to accommodate the characteristics of permeable asphalt pavements. Primary design parameters such as structural layer coefficients of permeable materials were successfully quantified based on literature reviews and parallel analyses. Comparable design thicknesses were obtained between the developed permeable pavement design (PPD) program and Korea pavement research program (KPRP) under different levels of traffic and subgrade load bearing capacity. |
