| 摘要： | The main objective of a snow and ice control operation strategy is to bring the road surface to a safe state for the driving public within a reasonable period of time. An important factor in this operation is the ability to determine the optimum amount of chemicals that need to be applied to achieve a safe surface condition. Over the past several years, personnel at many highway agencies in Europe, Japan, and the United States have come to believe that surface friction measurements may form the basis for improved winter maintenance operations and mobility. In light of all these factors, NCHRP initiated Project 6-14 to evaluate the feasibility of using friction indicators as tools for improving winter maintenance operations and mobility. Friction measurements for winter maintenance have been used in experimental research in the United States and in operational application (without sufficient supporting data) in some Scandinavian countries, while analytical and theoretical work, including the use of a neural network to predict friction from other data such as weather, traffic, and pavement condition, has been conducted in Japan. This study has found that the use of friction measurements to improve winter maintenance operations and mobility is feasible (especially when deceleration devices are used), but devices with an extra wheel may not represent a practical solution to friction measurement. / NOTE: Final rept. / Supplementary Notes: Prepared in cooperation with Virginia Polytechnic Inst. and State Univ., Blacksburg. and Virginia Transportation Research Council, Charlottesville.
