C09.49 - Pervious Concrete

SIGNIFICANCE AND USE
5.1 Tests performed at the same location across a span of years may be used to detect a reduction of infiltration rate of the pervious concrete, thereby identifying the need for remediation.  
5.2 The infiltration rate obtained by this method is valid only for the localized area of the pavement where the test is conducted. To determine the infiltration rate of the entire pervious pavement multiple locations must be tested and the results averaged.  
5.3 The field infiltration rate is typically established by the design engineer of record and is a function of the design precipitation event.  
5.4 This test method does not measure the influence on in-place infiltration rate due to sealing of voids near the bottom of the pervious concrete slab. Visual inspection of concrete cores is the best approach for determining sealing of voids near the bottom of the pervious concrete slab.
SCOPE
1.1 This test method covers the determination of the field water infiltration rate of in place pervious concrete.
Note 1: For permeable unit pavement systems, Test Method C1781/C1781M should be used. Test Method C1781/C1781M is functionally identical to this test method but includes added provisions for positioning and securing the test ring to a discontinuous surface. Both tests methods give comparable results  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.3 The text of this standard references notes that provide explanatory material. These notes shall not be considered as requirements of the standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
This test method provides a procedure for evaluating the potential resistance to degradation by impact and abrasion of pervious concrete mixtures. A common failure mode of pervious concrete pavements is raveling. This test allows the comparison of the relative potential resistance to raveling of pervious concrete mixtures of varying proportions and raw materials. In addition, in the field, raveling is caused by improper paste consistency, workability loss, inadequate compaction, and improper curingthis test method does not address any of these causes. There is no known correlation between this test method and the field performance of pervious concrete.
This information may be used to compare proposed mixture proportions, yet to be placed, but is not intended to be used for mixture qualification or jobsite acceptance testing.
This test method is applicable to pervious concrete mixtures containing coarse aggregate with a nominal maximum size of 25 mm [1 in.] or smaller.
This test method is only applicable to cylindrical specimens cast as described herein. The precision and bias have not been evaluated for drilled cores.

WITHDRAWN RATIONALE

Formerly under the jurisdiction of Committee C09 on Concrete and Concrete Aggregates, this test method was withdrawn in January 2022 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

SIGNIFICANCE AND USE
This test method is applicable to pervious concrete mixtures containing coarse aggregate with a nominal maximum size of 25 mm [1 in.] or smaller.
This test method applies to either core specimens or molded cylinders.
Density and void content determined by other test methods may produce different numerical results, which may not be comparable.
This test method allows one to choose one of two different drying methods. The following should be considered in selecting Drying Method A or B.
Drying Method A uses a lower temperature to determine the constant dry mass of the pervious specimen. Depending on the initial condition of the pervious specimen, obtaining the constant dry mass may take as long as one week or more. Drying Method B uses a much higher temperature and therefore the constant dry mass is attained much more quickly.
Specimens tested using Drying Method B shall not be used to determine other properties of the pervious concrete. If other physical properties such as strength or infiltration will be determined from the specimen, Drying Method A should be used for testing.
Drying Method B may produce lower densities and correspondingly higher void contents than Drying Method A. Results from the two methods should be treated separately and not combined.
Repeat testing of the same specimen using Drying Method A has been shown to produce dissimilar results. Only the first set of results should be considered.
Note 1—It is believed that exposure to high temperatures, as used in Drying Method B, may alter the void structure of the pervious concrete matrix by causing shrinkage cracks in the cement paste at the aggregate interface.
SCOPE

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
