Significance and Use
5.1 This test method provides a procedure for determining the density and void content of freshly mixed pervious concrete.
5.2 This test method is applicable to pervious concrete mixtures containing coarse aggregate with a nominal maximum size of 25 mm [1 in.] or smaller.
5.3 The measured fresh density may be used as verification of mixture proportions.
5.4 This method uses a standard consolidation procedure to measure fresh density and void content of a pervious concrete mixture as delivered. Test results are not intended to represent the density and void content of the in-place pervious concrete. This method shall not be used to determine the in-place void content or yield of the pervious concrete.
5.5 The fresh density and void content calculated from this test method may be different when comparing the results from Procedure A with Procedure B. Results are only comparable when obtained using the same procedure (Procedure A or B).
1.1 This test method covers determining the density of freshly mixed pervious concrete under standardized conditions and gives formulas for calculating the void content of pervious concrete. Test results are not intended to represent the in-place density and void content.
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 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 and health practices and determine the applicability of regulatory limitations prior to use. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.)
1.4 The text of this test method references notes and footnotes that provide explanatory information. These notes and footnotes (excluding those in tables) shall not be considered as requirements of this test method.
