There has been a growing trend over the past couple of decades to use liquids in a variety of ways in winter maintenance operations. We will take a look at how liquids work differently from solids, how liquids are being used, and what benefits agencies gain from using liquids. The bottom line is that liquids are perhaps a tool that you might want to consider adding to your winter maintenance toolbox, or if you have them in there already, perhaps you can expand your use of them.

Speaker Bio

Dr. Wilfrid Nixon is the President of the Professional Snowfighters Association, a North American based non-profit trade association dedicated to creating a community of good practice for all who are involved in the activities of winter maintenance. In 1987, Wilf moved to the University of Iowa, and became a faculty member in the College of Engineering, rising to the rank of Professor in 1998. Wilf worked at the University until June 2015, and is now Emeritus Professor there.  Wilf started his research in winter highway maintenance in the late 1980’s working initially on ways of improving snow plow performance. He has conducted research for a number of federal and state agencies, and has covered topics relating to plow and cutting edge performance, optimal chemical usage, snow fence design, plow and truck instrumentation, optimal uses of novel technologies in winter maintenance, and information management and decision making in winter maintenance. He has written over 100 papers and reports on his research, and has made numerous presentations around the world.  Wilf has worked on numerous committees and panels relating to winter maintenance at both the National and International level. He chaired the TRB committee on winter maintenance from 1998 to 2004 and has been a member of that committee from 1995 to 2008. He is currently an Emeritus member of that committee.   In 2015 Wilf joined the Salt Institute as Vice President for Science and the Environment and worked there until the Institute closed in 2019. In 2021, Wilf was named one of the Top Ten Public Works Leaders of the Year by APWA.
