1.1 This provisional test method covers a procedure for the extraction and recovery of asphalt binder from asphalt mixtures-both HMA (hot mix asphalt) and RAP (reclaimed/recycled asphalt pavement)-having a minimal effect on the physical properties of the asphalt binder recovered. It is intended for use when the physical properties of the recovered asphalt are to be determined. It can also be used to determine the quantity of asphalt binder in the HMA or RAP. Recovered aggregate may be used for sieve analysis.1.2 The values stated in SI units are regarded as the standard. Values in parentheses are for informational use.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.Note 1—Provisional standards require only subcommittee consensus and are published for a limited time of two years. This standard is being developed as a provisional standard because this method of extraction and recovery has been shown to produce more repeatable results than other methods of extraction and recovery that were tested. The subcommittee wishes to approve the method so that additional laboratories may use it to assist with the development of precision and bias statements.

4.1 This procedure measures the amount of the more volatile constituents in cutback asphalt. The properties of the residue after distillation are not necessarily characteristic of the bitumen used in the original mixture, nor of the residue which may be left at any particular time after field application of the cutback asphalt. The presence of silicone in the cutback asphalt may affect the distillation residue by retarding the loss of volatile material after the residue has been poured into the residue container.1.1 This test method covers a distillation test for cutback asphaltic (bituminous) products.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.

1.1 This specification covers asphalt roofing in sheet form, composed of organic roofing felt, saturated with asphalt and coated on both sides with an asphaltic compound which may or may not contain mineral stabilizer, and surfaced with powdered talc, mica, or other fine mineral matter to prevent sticking.1.2 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.>
