FIELD PERFORMANCE OF A POROUS ASPHALTIC PAVEMENT. FINAL REPORT
The Virginia Department of Transportation constructed a 2.52-acre parking lot of porous asphaltic pavement in Warrenton, Virginia. Runoff from the lot was collected and monitored for quantity, detention time, and quality. Prior to the lot opening for public use, three storms were successfully monitored. After the lot was opened to the public, four storms were monitored to ascertain whether traffic affected the lot's performance. It was determined that the lot was not performing as desired in the detention of runoff because of the slope across the parking lot, thus this portion of the research effort was terminated. The structural strength of the pavement has been monitored and has performed well for four years. Two recommendations that address design considerations were made as a result of this study: (1) The permeability of the underlying soil layers should be determined and considered as the main criterion in the design; and (2) The subgrade and riding surface of a porous asphaltic pavement should not have any slope.
