Laboratory tests have been carried out on many of the plastic clays from S.E. England which have given rise to highway earthwork slope failures. These included routine and special low-stress triaxial tests on tubed and reconstituted samples; in the special tests the samples were brought to failure along stress paths similar to those expected in the field. The tests gave values for the peak and critical strengths of the soils. The results indicated that the stability of the shallow slips was controlled by the critical or fully softened friction angle.
