THE EFFECTS OF TEMPERATURE ON THE PHYSICAL PROPERTIES OF COHESIVE SOIL

This paper reports the results of some experiments at coventry polytechnic, England, suggesting that temperature could affect shear strength, optimal moisure content and other important physical properties of a cohesive soil. The following tests were carried out on a brick clay at temperatures of 6, 20 and 35 degrees c: (1) atterberg limit; (2) optimal moisture content; (3) unconfined compression; (4) shear vane; (5) consolidation; and (6) sedimentation. The aim was to show what difference temperature might make to results obtained by accepted engineering practice. Some interesting trends of behaviour were found, although their correctness needs to be confirmed by a more extensive test programme. If these trends are correct, all laboratory tests would ideally be carried out at the temperature of the soil at the actual site being investigated. Failing that, a temperature of 20 degrees c should be specified in all standard tests, and the appropriate correction factors should be applied. (TRRL)
