Proposed System for Co-ordinating Spring Load Restrictions in Ontario

Abstract

Load restrictions are imposed by many road agencies to prevent excessive pavement damage on low volume roads during the spring thaw period. A variety of methods and criteria are used to establish restriction dates, creating uncertainty for commercial road users. New models were recently developed that use air temperature observations and forecasts from a provincial RWIS network to predict subsurface thaw depths and associated load restriction dates for surface treated highways. This provides scientifically-based projections to assist decision makers in determining load restriction dates to observed weather conditions in any year. Future developments will extend the predictions to any location in the province.
