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 polymermodified 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. 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. 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.
