More than 60% of Minnesota’s roadways consists of asphalt pavement. When transverse cracks occur in asphalt, our frigid winters can cause a secondary distress known as pavement tenting, crack heaving, or lipping. As ice accumulates in the base materials underneath, it causes pavement on both sides of the transverse cracks and joints to heave.
Left untreated, pavement tenting can accelerate the deterioration of asphalt near the transverse crack and potentially lead to potholes over time. While various preventive strategies have been used to address pavement tenting with mixed results, agencies do not have proper guidance for choosing the most effective mitigation strategies for a specific pavement.
Objective
The objective of this project is to develop a best practices manual for the mitigation of pavement tenting. It will include the creation of guidelines and decision trees on the most effective pavement tenting mitigation strategies based on the pavement’s age, current condition, remaining life, traffic, structure and subgrade materials.
