The objective was to determine the changes that moderately lithified, expansive clay shales undergo because of highway construction thereon. The ultimate goal was to acquire sufficient information so that highway design personnel could predict the results of the disruption of equilibrium conditions and could incorporate the predicted results into highway design. Late installation of instruments that either would not work or would not fit into the access tubes, that were extremely long (275 feet) because the researchers had to stay clear of the roadway surface, at a cut site in expansive clay shale that did not heave, produced inadequate data for useful analysis. "Unfortunately, because of difficulties encountered in field installation at the construction site, much pertinent data were not accumulated. The reasons for this loss and the effects on the results of the research are discussed throughout this report.
