A study was undertaken to search for new approaches to the problem of snow removal and ice control. Proven techniques of technology transfer were applied for the purpose of identifying technologies that have not yet been used for deicing purposes. Contracts with specialists and a 'brainstorming session' were used to determine strategies for search of computerized data banks. Although several approaches were identified, none are immediately useable. Results indicate that: (1) More information is needed on salt damage to the environment, highway structures, and vehicles in order to perform accurate cost-benefit analyses of alternative approaches. (2) More complete knowledge is needed on the effects of alternate chemical deicers. (3) Pavement heating is an expensive means of removing snow and ice but can be justified in special cases for safety or environmental reasons. (4) Two mechanical devices, snow plow with compressed air and a brush and blower system require further testing and development. (5) Research is required to identify a hydrophobic substance which can be applied to pavement to reduce ice adhesion. A brief cost estimate of the various approaches has been included.
