CTS Webinar: Keeping Roads Strong—Mitigating Pavement Tenting and Transverse Cracks

About the Event

Transverse cracks in asphalt pavement are a common challenge in Minnesota, often leading to a secondary problem known as pavement tenting (also called crack heaving or lipping). This occurs when ice buildup causes pavement to lift near a crack, which can accelerate deterioration and contribute to potholes.

This webinar showcased a research project that aimed to identify effective strategies to mitigate pavement tenting. The project developed a best practices manual with guidelines and decision tools to help agencies select solutions based on pavement age, condition, traffic levels, and soil type. Presenters discussed the research findings and how they can be applied to extend pavement life and improve roadway performance.

The webinar was held in conjunction with a CTS Transportation Infrastructure Council meeting.
