At MCDOT, we’re always keeping an eye on the best ways to maintain and extend the life of nearly 2,500 miles of County roads using different pavement preservation methods. 🚧

But eventually, every road reaches the end of the line β€” and no quick fix can bring it back. That’s when it’s time for a full pavement replacement.
First, crews remove the old roadway through a process called milling, digging out the worn asphalt and base materials.

Then, brand-new asphaltic concrete is installed, giving the road a fresh start and many more years of life ahead. πŸ›£οΈπŸ’ͺ

Arizona's winters are not only time for all the snowbirds to come back, but also the perfect time for our crews to provide roadway maintenance tasks like crack sealing.

Crack sealing prevents water from entering and weakening the pavement, which significantly slows roadway deterioration and extends the life of our streets.

Swipe to see what you should do if a crack sealing operation is present in your neighborhood.
