Description / Abstract:
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.
