Program to Reduce Deicing Chemical Usageby Byron N. Lord, Federal Highway Administration, United States,
Abstract: Over the years (since about 1948), the dependency on deicing chemicals has been increased to provide 'bare pavement' for safe and efficient winter transportation. Concern about the effects of sodium chloride (salt) on the environment and water quality and on automobile and highway bridge deck corrosion also increased with this chemical usage. Beginning in the late 1960's and culminating today with an $8 million research effort in the Strategic Highway Research Program (SHRP), the highway community - industry, government, and academia - has undertaken measures to minimize dependency on chemicals.
