Polymer Content of Polymer-Modified Emulsified

Asphalt Residue and Asphalt Binders

AASHTO Designation:T 302-05


AASHTO Designation:T 302-05 pdf free download

1.1.This test method is used to determine the percent concentration of a Styrene-Butadiene-Rubber (SBR), Styrene-Butadiene (SB), or Styrene-Butadiene-Styrene

(SBS) polymer in a polymer• modified asphalt binder or emulsified asphalt residue.

By using the infrared spectrum and the principles of Beer’s Law, the polymer content of the asphalt material can be determined.

1.2.This test method implies that the equipment used for the analysis is operated by experienced personnel according to the manufacturer’s directions for optimum

performance. A thorough understanding of infrared spectral analysis is recommended.

1.3.This standard involves hazardous materials, operations, or 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.
