Winter Road Maintenance Analysis

Our forensic engineers at FDi are experienced with accidents relating to winter road maintenance. We address maintenance issues by first reconstructing how the accident occurred. Next we investigate the roadway friction and condition, by assimilating forcasts, meteorological data, maintenance procedures and physical evidence. Finally, a determination is made regarding the appropriateness of the maintenance activities preceeding the accident.

Anti-Icing

Since 1991, Forensic Dynamics Inc. has been involved in issues relating to anti-icing campaigns. As of 1998, the firm has been involved with a tremendous number of skid tests, in order to fully understand these friction issues. In 1999, we constructed what is thought to be the world's first indoor, climate controlled, friction test facility to accurately measure friction characteristics under various temperature, humidity and application rates. As a result of this laboratory based research, numerous friction papers have been authored by Tim Leggett, P. Eng., P.E., Gerald Sdoutz, P. Eng, and Craig Luker, P. Eng.
Since this research has been completed, he has been asked to present our work at many venues across North America. Clients include chemical manufacturers, distributors, state and county agencies and the Federal Highways Administration.
