What goes into a highway? A bridge? Ask a materials engineer

Materials engineers evaluate everything from the rocks that go into cement to the reflective beads used in paints that stripe roadways to the bolts that help hold bridges together.

Signs are put to the test underneath Arizona's sun

Hard to believe, but after more than 200 blog posts we’re still surprised by some of the things we find out here at ADOT. For example, did you know there’s a small yard adjacent to an ADOT field office parking lot filled with dozens of sign samples?

ADOT group tests, evaluates rocks for use in asphalt mix

Placing asphalt friction course on a newly constructed road is sort of like icing a cake (stay with us here).
