This paper reviews the role of geotechnics in highway engineering. The importance of cooperation with the geologist is stressed and it is felt that in training engineers today insufficient attention is given to the behaviour of materials in the field. Failures still occur although an intensive road building programme has existed for a long time. The geotechnical expertise is still in the hands of specialists and not a part of the equipment of the design team. Soil engineers are too busy with laboratory tests. The real problem is to identify the situation in the field. This requires experience. Site investigations are too stereo-typed. Specifications are frequently written as if the ground conditions were already known. Field instrumentation is essential to check that the structure is behaving according to the design. The paper concludes with with a list of different approaches to the solution of geotechnical problems. The method adopted in any specific case will depend upon the scale, cost and the risk to life and property. (A) /TRRL/
