Standard Practice for Determining the Separation Tendency of Polymer from Polymer Modified Asphalt
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This practice describes a laboratory procedure for determining the tendency of polymer to separate from polymer modified asphalt under static heated storage conditions. The results of testing on material prepared according to this practice may be used as a guideline when formulating products or to establish field handling procedures. Large differences in test results between top and bottom specimens indicate that there is a degree of incompatibility between the polymer and the base asphalt.
1.2 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this 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 to determine the applicability of regulatory limitations prior to use.
Significance and Use
Purchasers of polymer modified asphalt need to be given guidelines on proper storage and handling procedures to maintain the integrity of material they have purchased. This practice provides a significant tool for understanding the characteristics of these materials as well as comparing various sources of supply.
