The objective of the research was to prepare a report evaluating the suitability of permeable pavements with stone reservoirs for shoulders from the perspectives of design, constructability, safety, maintenance, and longevity of the shoulder and the mainline.  A secondary objective was to develop a research plan to examine flow spreading, interception capacity, and hydraulics of the resulting runoff with respect to managing highway stormwater runoff and pavement drainage design.  The final report is posted here and a decision support tool is posted here.
