Proposed System for Co-ordinating Spring Load Restrictions in Ontario
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. (A) For the covering abstract of this conference see ITRD record 201310RT334E.
