WTI Research Laboratories
The Cold Climate Operations and Systems has made use of this lab, in particular with the following projects.
For this project laboratory analysis of potassium succinate (KSu) was conducted to assess the feasibility of use as a roadway deicer. Laboratory analysis included modified SHRP ice-melting testing, a differential scanning calorimetry (DSC) thermogram, and friction measurements to quantify performance. The overall results indicate that the performance of KSu is similar to that of NaCl at improving friction on roadways during snow and ice conditions. The results of DSC suggest that KSu can be applied as a roadway deicer at -5°C (23°F) and above. However, KSu does not function as a deicer at colder temperatures where salt brine will work (the generally agreed upon lowest working temperature for salt brine is 15°F [-9.5°C]). The results of the laboratory testing show that KSu functions as a roadway deicer with slightly lower ice-melting rates than salt brine.

The Corrosion and Sustainable Infrastructure Laboratory (CSIL) enables researchers to understand and mitigate the effects of materials corrosion on transportation systems as well as promote the sustainability of transportation infrastructure. WTIuses the lab to conduct problem-driven research in a trans-disciplinary manner with emphases on improved materials integrity, environmentally responsible maintenance and use of advanced technologies.
