Performance Assessment of Portland Cement Pervious Pavement. Report 4 of 4: Performance Assessment of a Pervious Concrete Pavement Used as a Shoulder for an Interstate Rest Area Parking Lot
A pervious concrete shoulder was constructed along a rest stop on Interstate 4 in central Florida. The shoulder was 90 feet long and 10 feet wide. The depth of pervious concrete was 10 inches. A 12 inch deep reservoir consisting of select pollution control materials was used beneath the pervious concrete. The shoulder was monitored over a one year period for wear and stormwater management. The shoulder was monitored for traffic counts recording approximately 500 axles per week. This use included stopping and starting and sometimes the stops were rapid as the truckers did prefer to park on the hard surface pervious concrete area. There was no visual wear noted on the concrete. An embedded single ring infiltrometer was used to monitor the infiltration rates. The rate of infiltration did not decrease with time. The average rates of infiltration over one year were 2.5 inches per hour at a head of zero to one inch; 4.8 inches per hour at a six inch head; and 6.3 inches per hour at a nine inch head. An acceptable rate of infiltration of these designs is 1.5 inches per hour. Water quality leaving the reservoir was about equal to rainwater quality. The amount of water from the collection pipe nearest the edge of pavement was about 50 times the volume from the collection pipe seven feet from the edge of pavement. The demonstration using pervious concrete was considered a success based on wear, water quality, and water quality considerations. It is recommended for other similar locations.
