Developing Friction Data to Support the Optimal Use of Pre-wet Deicing Salt for Enhanced Winter Mobility

Currently agencies in North America do not have reliable data to analyze the effectiveness and efficiency of its pre-wetting salt operations in districts facing localized and diverse traffic and weather conditions. Research is much needed to understand the influence of pre-wetting product type, pre-wetting ratio, and application rate of pre-wet deicing salt on the friction performance of deiced asphalt pavements, so as to generate the data needed for optimizing the use of pre-wet deicing salts for enhanced winter mobility. This UTC project will address this knowledge gap by conducting a customized laboratory testing program to lay the groundwork and developing a plan for subsequent field operational tests (FOTs). The ultimate goal is to develop data needed to support the optimal decisions related to the practices of pre-wetting salt and subsequent deicing to improve the mobility and safety of multimodal transportation systems in a fiscally and environmentally responsible manner.
