This paper summarizes the results of laboratory testing, computer performance modeling, and life-cycle cost analysis of fully permeable shoulder retrofits as a stormwater management strategy for highways. The use of these types of pavement is being considered as a potential best management practice for managing stormwater in a number of states. The deliverables from this research are a preliminary design procedure and an example set of catalogue-type design tables that can be used to design pilot and experimental fully permeable pavement test sections. The results obtained from the analyses in this study indicate that fully permeable pavements could be a cost-effective stormwater best management practice alternative as a shoulder retrofit on highways, as well as for maintenance yards, parking lots, and other areas with slow moving truck traffic. However, these results need to be validated in controlled experimental test sections and pilot studies before wider-scale implementation is considered. The findings from these full-scale experiments will be used to identify situations where fully permeable pavements are an appropriate best management practice, validate and refine the design method, undertake detailed life-cycle cost and environmental life-cycle assessments, and to prepare guideline documentation for the design and construction of fully permeable pavements.
