Evaluation of Impacts of Allowing Heavier Log Loads in Northern Wisconsin during Spring Thaw

Recent revisions of Wisconsin Statutes have increased the loads allowed for logging trucks on roadways during spring thaw. The increase to 98,000-pound loads on six axles supersedes previous regulations that allowed suspension of oversize and overweight permits for transportation of logs during thaw. This project intends to identify impacts of the rule change on asphalt pavement deterioration and performance. The effect of such loading on pavement life and condition has not been studied with regard to spring thaw. This research will focus on impacts of increased loading, what types of vehicles cause more damage than others and if this harm can be mitigated, what pavements may be vulnerable, and what tools would allow effective prediction of impacts. The Wisconsin Department of Transportation (WisDOT) will implement the study's cost-benefit analysis and recommendations for changes in practice by shaping preventative maintenance planning for affected roadways.
