The report describes past work and future directions in an ongoing project that is examining damage caused by the freezing and melting of soil under roads as well as measures designed to counteract this damage. The project is being conducted using three major research tools: interviews with highway officials in Sweden and other countries including Finland, Norway, England, and France; a literature search; results from the study 'Measures against the Harmful Effects of Frozen Soil on Road.' These results are from investigations of the following problem areas: frozen soil and its consequences; evaluation of measures against frozen soil; measures against frozen soil; strategy and tactics for counteracting the harmful effects. A distinction is made between measures to be taken on existing roads and those in connection with new construction. It is reported that for existing roads, no new 'revolutionary' methods have been developed. Many types of road deformation caused by freezing and thawing are discussed. The effect of such damage on traffic safety and possible damage to vehicles are examined. Both the economical aspects and physical processes of freezing and thawing are studied.
