DESIGNATIONS OF EXCAVATION CHARACTERISTICS FOR MATERIALS IDENTIFIED IN FIELD INVESTIGATIONS

This paper describes a system whereby geologic materials could be categorized according to their excavation difficulty during preconstruction field investigations and defines designations of excavation characteristics for each type of material. It is based on the premise that geologic formations, by their very nature, have rippability characteristics that are traceable, and thus predictable, from one locality to the next. The information obtained within right-of-way limits as a part of geologic mapping would be supplemented by numerous closely spaced auger borings. Examples of road and drainage excavation costs in various geologic environments and of costs of field investigations relative to total project costs are given. /Author/
