Recommended Actions

This is a major rehabilitation project to replace the worn surface, as well as remove and replace the deficient base layer pavement. 



Project Description

The 60.6 lane miles of existing pavement was last paved in 2016. Tire chains and studded tire use over the last 10 years have resulted in deep rutting in the pavement surface and potholing in an asphalt surface layer right above the joints or borders of an older concrete slab base.

Desired Project Outcome

A major rehabilitation project restores the existing pavement structure, enhances safety for motorists, and preserves one of the state’s largest and most important assets. Restoring the strength of the pavement structure extends the service life of the road and reduces long term maintenance needs.

The new surface improves safety by creating a smoother, more uniform surface that enhances vehicle control, reduces skidding, and improves water drainage. It also restores proper pavement texture and removes ruts and other surface distresses that can cause hydroplaning or sudden driver maneuvers.

Fresh, high contrast lane markings on the new surface are far more visible, especially at night or in wet conditions and help drivers stay in their lane reducing the risk of a crash.
