Effective Pre-Treatment Method for Events Beginning as Rain
Minnesota Department of Transportation (MnDOT) is requesting responses for a Clear Roads project that will evaluate pre-treatment options available to winter maintenance staff for winter events that begin with rain. Currently, the use of pre-treatment options such as liquid brine is rare before a winter storm that begins with rainfall because the rain will wash away the brine before it can serve its purpose. However, by experimenting with various materials and differing mixture proportions, and altering spread rates, options may be available to effectively counter the effects of snow storms with preceding rainfall. Research recommendations can be used to inform the decision-making of state departments of transportation (DOTs), municipalities and other winter maintenance practitioners when choosing a pre-treatment option for winter events that begin with rain.
