Water quality and restoration in a coastal subdivision stormwater pond. Hide Additional Record Data. The field measurements were performed using six experimental section designs with different permeable pavement surface types including pervious concrete, porous asphalt and permeable interlocking ashm pavers.
This was placed over a mm 4 in. 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 satm.
The pervious concrete pavement industry elected to use method 2 i. On both sites, the jointing stones are asmt between the joints under the ring and filled with plumbers putty to further direct the water downward.
Visual inspection of concrete cores is the best approach for determining sealing of voids near the bottom of the pervious concrete slab. Understanding from a Laboratory Investigation.
This is likely due to the speed and economy of conducting tests in this manner. This test method is intended for use on soils with infiltration rates between 14 in.
Data and experience from Bean, Atsm, and Drake confirm that C is suitable for testing the surface infiltration of PICP and Bean extends its use to successfully testing concrete grid pavements.
Historical Version s – view previous versions of standard. The surface infiltration rates of both PC sections were about twice as large as PICP, and all three were more than one order of magnitude larger than PA. It is recommended that future surface infiltration testing should strategically select fixed testing locations based on expected clogging patterns. This study was undertaken adtm compare measured values for both methods in the field on a variety of permeable pavements used in current practice.
The lowest values were due to clogging from fines. 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.
As the use of these asym 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. Randomly selected locations across each area were tested periodically cc1701 monthlyand other measurements were made quarterly at fixed locations.
ASTM C currently requires that the mass of infiltrated water be determined so that value can be entered into a formula that calculates the surface infiltration rate. Surface infiltration is a key performance indicator of both pavement types. Are you axtm for Six Month Update November through April The C171 method is written specifically for pervious concrete, so additional research is needed to determine the applicability of this method to other permeable pavement types.
The solids concentrate and collect at this location as the runoff infiltrates through the surface. 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.
To determine the infiltration rate of the entire pervious pavement multiple locations must be tested and the results averaged. Terry Lucke 11 Estimated H-index: Gordon Mitchell 21 Estimated H-index: These notes shall not be considered as requirements of the standard. Maupin 1 Estimated H-index: Masoud Kayhanian 30 Estimated H-index: Permeability measurement and scan imaging to assess clogging of pervious concrete pavements in parking lots. Table 1 provides the test data for three test locations.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Both tests methods give comparable results.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Borst reports using a modified version of C to test PICP, pervious concrete, and porous asphalt as part of a satm visible evaluation of these pavements.
ASTM C1701/C1701M – 17a
asmt A comparison of thermal performance of different pavement materials. Jun Chen 5 Estimated H-index: Field investigation of clogging in a permeable pavement system building research and information. While including porous asphalt surface testing in C may not fall exactly within the scope of Committee C09, including it in C could help compare performance among the most common permeable pavements.

ASTM C/CM – 17a – Standard Test Method for Infiltration Rate of In Place Pervious Concrete
An additional c101 parking row at the northern end of the lot was surfaced with pervious concrete PC-N. Log In Sign Up. A key consideration on locating the ring is to frame the paver joint pattern within the ring. 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 the rings.
Xstm 9 Estimated H-index: Weiss 10 Estimated H-index: Mapping hazard from urban non-point pollution: Comparing the two pervious concrete sections, the 0.
Brattebo University of WashingtonDerek B. The modeling clay molds quickly and creates a seal between the ring and pavers.
