TL;DR: In this paper, the authors describe how pervious concrete as a paving material has generated tremendous interest because of its ability to allow water to flow through itself to recharge groundwater and minimize storm water runoff.
Abstract: This publication describes how pervious concrete as a paving material has generated tremendous interest because of its ability to allow water to flow through itself to recharge groundwater and minimize storm water runoff. This introduction to pervious concrete pavements reviews its applications and engineering properties, including environmental benefits, structural properties, and durability. Both hydraulic and structural design of pervious concrete pavements is discussed in the publication and construction techniques are also described.

TL;DR: In this article, the authors studied the effect of the water to cement ratio (W/C), admixture and mixing time on porous concrete properties and showed that the strength of porous concrete could be estimated from strength equation of porous brittle material.

TL;DR: In this article, four permeable pavement applications in North Carolina's Coastal Plain were constructed and monitored to determine their effectiveness of reducing runoff quantity and improving water quality, and two PICP sites were monitored for water quality.
Abstract: Four permeable pavement applications in North Carolina’s Coastal Plain were constructed and monitored to determine their effectiveness of reducing runoff quantity and improving water quality. Sites were either constructed of permeable interlocking concrete pavers (2), porous concrete (1), or concrete grid pavers (1). One site of each pavement type was monitored for runoff reduction for periods ranging from 10 to 26 months. Measured runoff depths from rainfall events over 50 mm were used to determine permeable pavement equivalent curve numbers for the sites, which ranged from 45 to 85. Only the two permeable interlocking concrete pavement (PICP) sites were monitored for water quality. Runoff and exfiltrate samples were intended to be collected, in addition to runoff monitoring, from the Swansboro PICP site. However, no runoff was produced during this study from the Swansboro PICP site for rainfall events up to 88 mm . From exfiltrate concentrations, nutrient retention was estimated to be 3.4 and 0.4 kg∕ha∕...

TL;DR: In this paper, a parking lot in eastern North Carolina consisting of four types of permeable pavement and standard asphalt was monitored from June 2006 to July 2007 for hydrologic differences in pavement surface runoff volumes, total outflow volumes, peak flow rates, and time to peak.
Abstract: A permeable pavement parking lot in eastern North Carolina consisting of four types of permeable pavement and standard asphalt was monitored from June 2006 to July 2007 for hydrologic differences in pavement surface runoff volumes, total outflow volumes, peak flow rates, and time to peak. The four permeable sections were pervious concrete (PC), two types of permeable interlocking concrete pavement (PICP) with small-sized aggregate in the joints and having 12.9% (PICP1) and 8.5% (PICP2) open surface area, and concrete grid pavers (CGP) filled with sand. The site was located in poorly drained soils, and all permeable sections were underlain by a crushed stone base layer with a perforated underdrain. All permeable pavements significantly and substantially reduced surface runoff volumes and peak flow rates from those of asphalt (p
