The multiciplicity of problems faced by the soils engineer in a transportation-oriented department is illustrated in this RECORD, which includes papers on topics that are as widely separated as the effect of negative skin friction on piles and the capability of an unsurfaced roadway. This RECORD also includes papers of interest to the bridge engineer. Those papers deal with influence values for vertical stress distribution beneath uniformly loaded circles, uncertainty of settlement analysis, vertical sand drains, and dragdown due to negative skin friction. The planner and those responsible for route location will be interested in the applications of air-photo interpretation to the definition of soils problems and of the generalized regional concept to highway soils considerations. Transportation departments, increasingly involved in the design of roads in wilderness areas, will find the road capability study report helpful. The more sophisticated material characteristics, methods of arriving at trade-offs through values of relative strength, and improved soil bituminous mix design are discussed in several papers that will benefit the materials engineer and the structural pavement designer. Safety and convenience are improved with improved methods of in situ strength evaluation.
