Structural Materials Testing

Recording and storing results of concrete cylinder testing performed during road construction is a function of numerous construction offices throughout Arizona. Through a number of computer applications, these testing results are captured, stored, and regularly utilized internally. This information is provided for the general public as well as current and potential vendors wishing to do business with ADOT.

If tests fail, projects stop
As in her job with ADOT, Kelly Baum gets to play in dirt to make sure the materials used in construction projects are up to the task.
 Students from Copper King Elementary School in Phoenix learned how math and science skills are used to build roads and other infrastructure while touring an ADOT Materials Lab.
A visit to the ADOT Materials Lab in Phoenix demonstrated how what taught in science, technology, engineering and mathematics helps those who build and maintain state highways.
Pavement mixture
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.
You might think that highway construction is all about big machinery, heavy-duty vehicles, massive structures and materials by the ton – but it’s not.
Sign sheeting samples are put to the test in the Arizona 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?
