Real-time measurement of tire-road friction coefficient is extremely valuable for winter road maintenance operations and can be used to optimize the kind and quantity of the deicing and anti-icing chemicals applied to the roadway. In this project, a wheel based tire-road friction coefficient measurement system is first developed for snowplows. Unlike a traditional Norse meter, this system is ba...

Results from disaster research suggest that methods for coordination between individual emergency responders and organizations should recognize the independence and autonomy of these actors. These actor features are key factors in effective adaptation and improvisation of response to emergency situations which are inherently uncertain. Autonomy and adaptability are also well-known aspects of a ...

This paper describes the use of thermodynamic modeling to predict reaction products and properties cementitious pastes containing fly ash. A pore partitioning model is used estimate gel capillary volumes. The paste performance predicted in terms its porosity, compressive strength, formation factor, deicing salt damage susceptibility. proposed quantify refinement that occurs when ash used. Compa...

Vast networks of roads cover the earth and have numerous environmental effects including pollution. A major component of road runoff in northern countries is salt (mostly NaCl) used as a winter de-icing agent, but few studies of effects of road salts on aquatic organisms exist. Amphibians require aquatic habitats and chemical pollution is implicated as a major factor in global population declin...

This study aimed to carry out a systematic analysis of the literature on environmental impactsof waste resulting from year-round maintenance roads (WMR) with deicing agents. The impacts economic factors and environment at all stages life cycle were systematically examined, taking into account engineering technological efficiencies, direct, indirect, prolonged deferred effects. A structural-inte...

Solidago sempervirens, a halophytic goldenrod native to coastal dunes and marshes of eastern North America, has expanded its range inland along roads in parts of the northeastern United States during the past 20–30 yr. This expansion has been concurrent with the application of deicing salts on roadways in winter. During the same period, the species has appeared inland along the St. Lawrence wat...
