Abstract:

An investigation into a recycled asphalt pavement built in 1989 on US212 between La Plante and the Missouri River which had prematurely failed revealed an unusually high concentration of metals in the asphalt cement. These metals, capable of promoting the oxidation of asphalt, could not be attributed entirely to either the fines or the stones in the asphalt mix. The types of metals found (by inductively coupled plasma emission spectroscopy, ICP) plus the nature of the organic compounds identified (by gas chromatography I and mass spectrometry, GC/MS) in the asphalt cement suggest that either used lubricant or a residue of waste oil may have contaminated the asphalt used in the construction of the pavement built between LaPlante and the Missouri River.
