APPLICATION OF INSTRUMENTAL METHODS FOR EVALUATING HIGHWAY MATERIALS - FOURTH PROGRESS REPORT: GAS CHROMATOGRAPHY

PYROLYSIS GAS CHROMATOGRAPHY HAS BEEN USED TO CHARACTERIZE POLYMERS IN ADDITION TO THOSE INCLUDED IN A PREVIOUS REPORT (MDSH RESEARCH REPORT NO. R-666), AND TO DETERMINE NEOPRENE CONTENT OF PREFORMED PAVEMENT JOINT SEALS IN A ROUGH QUANTITATIVE MANNER. A STANDARD WET CHEMICAL METHOD WAS ALSO USED TO ACCURATELY DETERMINE THE NEOPRENE CONTENT OF PAVEMENT JOINT SEALS. VARIATIONS IN NEOPRENE CONTENT DID NOT CRITICALLY AFFECT PHYSICAL PROPERTIES OF THE SEALS. A CONVENTIONAL GAS CHROMATOGRAPHIC METHOD IS DESCRIBED FOR ANALYSIS OF THE THINNER (VOLATILES) OF TRAFFIC PAINTS ON UNSEPARATED SAMPLES TAKEN DIRECTLY FROM THE CAN. A NUMBER OF POLYMER COMPOUNDING ADDITIVES (PLASTICIZERS, ANTIOXIDANTS) WERE ANALYZED BY CONVENTIONAL GAS CHROMATOGRAPHY AND THESE CHROMATOGRAMS, RETENTION TIMES, AND DETECTOR RESPONSE FACTORS ARE INCLUDED. /AUTHOR/
