ASTM C/CM – 17a – Standard Test Method for Infiltration Rate of In Place Pervious Concrete
There was no difference between maintained and unmaintained area surface infiltration rates, likely due to the newness of the surfaces.

These notes shall not be considered as requirements of the standard. Hide Additional Record Data. The longevity was attributed to the clogging mechanism.
To determine the infiltration rate of the entire pervious pavement multiple locations must be tested and the results averaged. ASTM C is an inexpensive and rapid test method for measuring surface infiltration by simulating a small hydraulic head on c7101 surface test area like those generated by intense rain storms and contributing runoff.
ASTM C1701/C1701M – 17a
Remember me on this computer. Jun ChenHui Li. The research objectives and parameters for this multi-year monitoring project are shown in Table 3. The literature demonstrates Chopra and Vancura that permeable atsm can experience a reduction in their surface infiltration rates especially if not maintained with vacuum sweeping.
The unweighted means for pervious concrete were 1. Six Month Update November through April 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, cc1701 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 Understanding from a Laboratory Investigation.
Water quality and restoration in a coastal subdivision stormwater pond. Experimental investigation on evaporation rate for enhancing evaporative cooling effect of permeable pavement materials.
Standard Test Method for Infiltration Rate of In Place Pervious Concrete
The modeling clay molds quickly and creates a seal between the ring and pavers. Surface infiltration asstm are measured monthly in both areas with a modified version of ASTM C to characterize the clogging potential of each surface and when cleaning might be required.
Show Additional Record Data. This framed area should represent the percentage of open area in the overall surface to best characterize surface infiltration.
Mapping hazard from urban non-point pollution: Multiple measurements c17701 performed at five locations on each pavement test section. She is also investigating water volume and pollutant removal from these pavements. The results showed that: With almost three ast, 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.
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. Masoud Kayhanian 30 Estimated H-index: Jump to main content.
He moved to a single ring infiltrometer due to high surface infiltration rates of the permeable pavements tested and the volume of water required for maintaining hydraulic heads within asym rings.
Prowell 9 Estimated H-index: Both tests methods give comparable results. Even when c7101 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.
Broadening the application of ASTM C to characterize the surface infiltration of more than just pervious concrete enables an objective comparison of the performance other pavement systems designed to reduce stormwater runoff. The surface infiltration rates of both PC sections were qstm twice as large as PICP, and all three were more than one order of magnitude larger than PA.
The primary solids source was the upgradient impermeable asphalt driving lanes. The field measurements were performed using six experimental section designs with different permeable pavement surface types including aetm concrete, porous asphalt and permeable interlocking concrete pavers.
Surface infiltration is a key performance indicator of both pavement types. Borst reports using a modified version of C to test PICP, pervious concrete, and porous asphalt ast, part of a nationally visible evaluation of these pavements.
Sara Simona Cipolla 3 Estimated H-index: Along these lines, proposed changes to C include the following: It is recommended that future surface infiltration testing should strategically select fixed testing locations based on expected clogging patterns. This was constructed in lieu of a drywell drainage system.
