Road asphalt oxidized at 100 and 130ยฐC was examined by gel permeation chromatography (g.p.c.) and infrared spectroscopy. Increasing the sample concentration produced a relative increase in absorbance in the early part (region 1) of the g.p.c. chromatogram, suggesting that intermolecular associations
