Effectiveness of anti-icing operations for snow and ice control of parking lots and sidewalks

Abstract

This paper describes an empirical study aimed at investigating the performance of the anti-icing strategy for snow and ice control of parking lots and sidewalks. The research is motivated by the need to address several key questions concerning various operational decisions related to the anti-icing strategy, including its relative effectiveness under different weather and site conditions, treatment options, and optimal application rates. Extensive field tests were conducted under traffic controlled environment and variety of weather events using regular solid road salt, brine, and two other liquid alternatives. Data collected from these tests was used to analyze the performance of anti-icing operations such as friction level, bare pavement regain time, and the effects of various external factors such as pavement temperature and application rate. The research has concluded with findings that are directly applicable in real world winter maintenance practices.Résumé : Le présent article décrit une étude empirique d'examen du rendement d'une stratégie antigivrage pour le contrôle de la neige et de la glace sur les stationnements et les trottoirs. Cette recherche découle du besoin de traiter de plusieurs questions clés concernant diverses décisions opérationnelles reliées à la stratégie antigivrage, incluant son efficacité relative sous différen-tes conditions climatiques et de site, les options de traitement et le taux optimum d'application. Des essais de terrain à grande échelle ont été réalisés dans un environnement de circulation contrôlé et sous diverses conditions climatiques et de site; du sel de voirie solide ordinaire, de la saumure et deux autres liquides ont été utilisés. Les données colligées lors de ces essais ont servi à analyser le rendement des opérations antigivrage quant à la friction, le temps requis pour revenir à la chaussée dégagée et les effets de divers facteurs externes tels que la température de la chaussée et le taux d'application. La recherche a conclu les résultats sont directement applicables dans les pratiques concrètes d'entretien des chaussées durant l'hiver.

Bioinspired Surfaces with Superwettability for Anti‐Icing and Ice‐Phobic Application: Concept, Mechanism, and Design

“…Ice accumulation is not only a concern for drivers, but also the cause for personal injuries on walkways due to numerous slipping and falling. [1][2][3][4][5][6][7][8][9][10][11][12][13] When ice accumulates on the wings of aircraft, turbine engine structures, or insulators and transmission lines on power systems, it will impose serious problems and cause some disastrous damage in the aircraft and power industry. [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32] In the winter of 2008-2009, frozen rain lasted for more than three weeks in Hunan and Jiangxi provinces, causing downfall of 37% of Ice accumulation poses a series of severe issues in daily life.…”

“…Ice accumulating on solid surfaces can cause serious problems on roads, aircrafts, power lines, ships, and some energy equipment. Statistics indicates that 10–15% of roadway accidents are related to weather conditions, which have caused thousands of human injuries and deaths and millions of dollars in property damage annually.…”

Salt Gradation Analysis for Winter Road Maintenance

“…In Canada, a study conducted by researchers at the University of Waterloo [14] concluded that salt gradation has great impact on the performance of the de-icing salt. A comparative study was conducted between coarse road salt with average particle size of almost 6.5 mm (the majority of the material being in the range of 4 to 9 mm); and fine road salt with average particle size of 4.3 mm (the majority of the material within the range of 1.6 to 7 mm); and another road salt (referred to as UW salt) with average particle size of 2.5 mm (the majority of the material <5 mm).…”

Laboratory Investigation and Efficiency of Deicing Materials Used in Road Maintenance

“…Compared to solid salt, brine was found to be more effective when the mass amount of salt (NaCl) used was considered in test sites treated by solid salt and brine under similar winter events (Hossain et al 2014). In practise, spreading of saturated brine takes effect immediately if there is frost or ice on the road, whereas dry or prewetted salt takes time to become effective (Fonnesbech 2001).…”
