Abstract

Scope: This practice covers two methods for recovering the residue from emulsified asphalts such as those specified in M 140 and M 208, using low-temperature evaporative techniques that are similar to pavement conditions. The recovered residue can be used for further testing as required. The values stated in SI units are to be regarded as the standard. This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns 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.
