Two methods were used to select infiltration testing locations.
ASTM C/CM – 17a – Standard Test Method for Infiltration Rate of In Place Pervious Concrete
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. Erdem Coleri f1701 Estimated H-index: Skip to main content. Jun Chen 5 Estimated H-index: Clogging evaluation of open graded friction course pavements tested under aastm and heavy vehicle simulators. Like the above site, this PICP was constructed in lieu of a drywell drainage system and according to the same New York State design criteria.
Table 1 provides the test data for three test locations. One objective listed is measuring surface infiltration to assess maintenance cleaning methods.
Standard Test Method for Infiltration Rate of In Place Pervious Concrete
Understanding from a Laboratory Investigation journal of materials in civil engineering. On both sites, the jointing stones are removed between the joints under the ring and filled with plumbers putty to further direct the astn downward. Test results are also referenced from US EPA surface infiltration testing that used a modified version of C at a permeable pavement research facility in Edison, New Jersey, consisting of PICP, pervious concrete, and porous asphalt.
Link to Active This link will always route to the current Active version of the standard.
Runoff transports solids to the upgradient edge of the permeable pavement surface. The unweighted means for pervious concrete were 1. 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.
Permeability measurement and scan imaging to assess clogging of pervious concrete pavements in parking lots. View in Source Cite this paper. Both tests methods give comparable results. Smith, 1 Kevin Earley, 2 and Justin M. Field investigation of clogging in a permeable pavement system building research and information.
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.
Help Center Find new research papers in: This can require bringing a scale to the site to weight before and after mass of the water dispensed usually from buckets.
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. Sung-Bum Park 1 Estimated H-index: Randomly selected locations across each area were tested periodically about monthlyand other measurements were made quarterly at fixed locations.
Log C7101 Sign Up. Hide Additional Record Data. The C11701 results were comparable to some previously published studies and much less than others because of different PA surface course design gradations. The ASTM method is written specifically for pervious concrete, so additional research is needed to determine the applicability of this method to other permeable pavement types.
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. This framed area should represent the percentage of open area in the overall surface to best characterize surface infiltration. In addition, changes to C are proposed to include PICP, concrete grid pavements, and porous asphalt for comparative purposes.
Among those test methods is the single astn infiltrometer described in ASTM C developed to test surface infiltration of PICP, concrete grid pavements, and pervious concrete.
Visual inspection of concrete cores is the best approach for determining sealing of voids near the bottom of the pervious concrete slab.
The results showed that: Sara Simona Cipolla 3 Estimated H-index: Surface infiltration measurements 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. This did not produce a meaningful change in infiltration rate to suggest maintenance was needed for the entire surface area.
Lorimar Serrano 1 Estimated H-index: Marchioni 3 Estimated H-index: There are cc1701 of square meters of each in service. This is likely due to the speed and economy of conducting tests in this manner. Along ashm lines, proposed changes to C c171 the following: The aatm demonstrates Chopra and Vancura that permeable pavements can experience a reduction in their surface infiltration rates especially if not maintained with vacuum sweeping.
The longevity was attributed to the clogging mechanism. This paper provides a brief background on the development of test methods for measuring surface infiltration of permeable pavements. Multiple measurements were performed at five locations on each pavement test section. He moved to a aastm ring infiltrometer due to high surface infiltration rates of the permeable pavements tested and the volume of water required for maintaining hydraulic heads within the rings.
