Significance and Use
3.1 The procedure described in this practice is used to obtain a residue from an emulsified asphalt that may be used for further testing in devices such as a dynamic shear rheometer. The lower evaporative temperatures of this procedure provide conditions that are very close to that of application techniques for these materials. This practice could be used in place of recovery techniques such as those of Test Methods and , when the temperatures used in those standards would negatively affect the residue.
1.1 This practice covers a method for recovering the residue from emulsified asphalts such as those specified in Specifications and using a low temperature evaporative technique that is similar to pavement conditions. The recovered residue can be used for further testing as required.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are 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.
