Material application methodologies guidebook
This guidebook will help superintendents and supervisors determine the most sustainable and effective material types, application timing, methods, and rates for the particular snow and ice conditions they encounter. It is based on best practices from interviews with state and local agencies.
The guidebook also has single-page handouts that operators can print and use for quick reference. Handout topics include deicing and antiicing, sanding, and pre-wetting.
Mobile technologies for assessment of winter road conditions
This study provides a comprehensive and comparative analysis of four commercially available mobile road weather information systems (RWIS) sensors.
The study compared the four sensors’ performance while measuring air temperature, surface temperature, relative humidity, surface condition, water film thickness, and friction. The evaluation also compared qualitative aspects of the sensors such as installation methods.
The project found that overall, sensors performed similarly across all parameters. Thus, the report recommends that agencies select sensors based on the factors they value most, including both parameter accuracy and factors such as cost and installation.
