Abstract

Approximate locations of each new highway facility are determined from reconnaissance surveys. The reconnaissance plan with a topographic sheet is presented to the geologist who prepares a geologic strip map along the lines shown. This geologic map informs the engineer regarding the kinds of soil materials, the location of bedrock outcrops, and the various land forms to be traversed by the highway. Locations where seismic explorations are necessary are indicated. A geologic survey is conducted to indicate all available sources of highway construction materials: Trap rock gravel, sand, etc. Some of the specific applications of geological interpretations and seismic explorations to the location and design of highways in massachusetts are described.
