Abstract:

Pervious pavement systems are now being recognized as a best management practice by the Environmental Protection Agency and the state of Florida. The pervious concrete system is designed to have enhanced pore sizes in the surface layer compared to conventional pavement types, encouraging flow of water through the material. This research project investigated the infiltration rates, rejuvenation techniques, sustainable storage of the components and complete systems, water quality, and the strength properties of pervious concrete pavements. The work was conducted at the field labs of the Stormwater Management Academy at UCF. Pervious concrete pavement systems are able to perform well considering the high level of imposed sediment accumulation throughout the 22-month study period. Out of 119 tests conducted on these sections, only thirteen tests recorded rates below 2.0 in/hr. The pervious concrete pavement systems can be expected to perform above 2.0 in/hr under normal “light to medium” sediment accumulation conditions without any maintenance and the infiltration rate can fall below 2.0 in/hr if under intense “heavy” sediment loading. A standard vacuum sweeper truck to rates above 2.0 in/hr, however, can rejuvenate these systems. The compressive strength values for pervious concrete samples cored from the installation at the field laboratory ranged from 988 – 2429 psi while the compressive strength range of the 8 x 4 cast in place samples was in the range 364 – 1100 psi. The total porosity measured was around 32% while the effective sustainable porosity was found to be around 27%. Water quality results indicate increase in nitrogen, ammonia, total and ortho-phosphate but this could be attributed to the use of local soils for the sub-base, which likely leached nutrients.
