Using road weather information systems (RWIS) to optimize the scheduling of load restrictions on Northern Ontario's low-volume roads

Seasonal shifts in moisture and temperature within the pavement can affect the bearing capacity of the roadway, especially in Northern Ontario where low volume roads are challenged by frequent freeze-thaw cycles. Seasonal load restrictions (SLR) are implemented every year on Ontario's secondary and tertiary highways to protect the road infrastructure. However, each time loaded trucks are allowed on a weakened pavement, premature deterioration …
