Modifications to C are proposed that include use of 1 modeling clay to seal the ring to the pavement in hot weather; and 2 graduated bucket s to determine the mass of infiltrated water.
The unweighted means for pervious concrete were 1.
Permeable Pavements in Cold Climates: Surface infiltration is a key performance indicator of both pavement asgm. After pre-wetting, ASTM C test method was conducted three times over the first 11 months of service that resulted in an average infiltration rate of 2. Masoud Kayhanian 30 Estimated H-index: Figure 4 illustrates the apparatus.
Infiltration rates were significantly different across each pavement type. With almost three years of use, maintenance has yet to be required, although infiltration has decreased in areas immediately downgradient of contributing drainage areas and to a greater extent where disturbed soil was present.
Standard Test Method for Infiltration Rate of In Place Pervious Concrete
Environmental Protection Agency constructed a 0. Her observations regarding both pavement types are that they require regular vacuum sweeping in order to maintain surface infiltration rates.
Experimental investigation on evaporation rate for enhancing evaporative cooling effect of permeable pavement materials.
This framed area should represent the percentage of open area in the overall surface to best characterize surface infiltration. Table 1 provides the test data for three test locations.
Hui Li 11 Estimated H-index: ASTM C currently requires that the mass of infiltrated water be determined asrm that value can be entered into a formula that calculates the surface infiltration rate. Randomly selected locations across each area were tested periodically about monthlyand other measurements were made quarterly at fixed locations.

As a sister sustainable pavement to pervious concrete, permeable interlocking concrete pavement PICP has seen increased use for stormwater management and low impact development LID.
Booth University of Washington. X1701 primary solids source was the upgradient impermeable asphalt driving lanes.
ASTM C1701/C1701M – 17a
Jun Chen 5 Estimated H-index: US EPA research objectives and parameters measured at the Edison, New Jersey, permeable pavements research facility Monitoring Objective Parameters Measured Hydrologic performance Volume, exfiltration rate Water quality Soils, indicator organisms, metals, nutrients, organic performance compounds Urban heat island effects Net radiation, infrared radiation, temperature Maintenance effects Surface infiltration rate, visual assessment Use Car counter, visual assessment Infiltrating water Water depth, redox, pH, conductivity, chloride parameters Potential use of pervious concrete for maintaining existing mature trees during and after urban development.
This did not produce a meaningful change in infiltration rate to suggest maintenance was needed for the entire surface area. The research objectives and parameters for this multi-year monitoring project are shown in Table 3.
The field measurements were performed using six experimental section designs with different permeable pavement surface types including pervious concrete, porous asphalt and permeable interlocking concrete pavers.
This could eliminate the use of a scale on the test site. Borst reports using a modified version of C to test PICP, pervious concrete, and porous asphalt as part of a nationally visible evaluation of these pavements. As the use of these pavements increases, a definitive test method is needed to measure hydraulic performance and to evaluate clogging, both for performance studies and for assessment of permeability for construction quality assurance and maintenance needs assessment.
Maupin 1 Estimated H-index: Even when one test measured that the surface was clogged near the upgradient edge, the effect was generally diluted by averaging with the larger infiltration rates from unaffected locations. In ascending cost order they include 1 visual inspection during or immediately after a rainstorm for ponding; 2 measuring surface infiltration on sampled small areas; 3 generating synthetic rainfall and runoff for a distinct rain event which often involves a rain simulator; and 4 continuous monitoring of rainfall and surface runoff usually over a period years.
Table 2 provides the test data. It is recommended that future surface infiltration testing should strategically select fixed testing locations based on expected clogging patterns.
Jun-kang Lan 1 Estimated H-index: ASTM C is an inexpensive and rapid test method for measuring surface infiltration by simulating a small hydraulic head on the surface test area like those generated by intense rain storms and contributing runoff.
This can require bringing a scale to the site to weight before and after mass of the water dispensed usually from buckets.
For periodic monthly testing, six randomly-selected locations were tested on each of the four permeable pavement sections from December to MaySeptember to Mayand August ASTM C test apparatus at a public library parking lot After pre-wetting, ASTM C test method was conducted in April, during the first months of service that resulted in an average infiltration rate of 3.
