Abstract
A one-year research project was sponsored by Texas Department of Transportation and conducted by the University of Texas to evaluate the Cape Seal process as a pavement rehabilitation technique. During the research project, most of the Cape Seal projects which had been constructed within the State were visited. Very successful projects as well as serious failures were noticed during the visits. Most of the failures noticed could be contributed to the failure of the underlying chip seal due to aggregate loss or insufficient chip seal-pavement bond. Permeability tests, shear tests, and loaded wheel tests were performed on laboratory made Cape Seal specimens. Permeability tests were also conducted on field cores. Permeability of micro-surfacing was found to be at least equal to that of typical hot mix asphalt overlays. High temperature repeated shear tests indicated that most of the debonding failure occurs at the interface of the chip seal and the underlying pavement rather than the interface of the chip seal and the micro-surfacing.
