Significance and Use
5.1 The asphalt retention is a test procedure for full-width paving fabrics. The use of this test method is to establish an index value by providing standard criteria and a basis for uniform reporting.
5.2 This procedure is applicable for testing conditioned specimens (see 8.1). The results obtained may vary, depending on which type of asphalt cement is used for the test. Unless stated otherwise, use A.C. 20 as defined in Specification D3381/D3381M or equivalent asphalt cement.
5.3 This procedure is applicable whenever it is desired to determine an index asphalt retention of paving fabric.
5.4 If it becomes necessary for the purchaser and the seller to use this test method for acceptance testing, the statistical bias, if any, between the purchaser's and seller's laboratories should be determined. Such comparison is to be based on specimens randomly drawn from the sample of geotextile being evaluated.
1.1 This test method covers a procedure for determining the asphalt retention for paving fabrics. Paving fabrics are used in a fabric membrane interlayer system in pavements before the placement of an asphaltic overlay.
1.2 This test method shows the values in both SI units and inch-pound units. SI Units is the name for the system of metric units known as the International System of Units. Inch-pound units is the correct name for the customary units used in the United States. The values in inch-pound units are provided for information only.
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.
