Are Aggregates & HMA Important?
What about PCC?U.S. Concrete Production in 2004 was 430,500,000 cubic yards
Tennessee 2004 Concrete Production was 6,888,000 cubic yards

We are Making Materials Greener
(Actually More Environmentally Friendly but we
can also color materials green)
While Enhancing Material Performance
We Helped Rewrite the Book on CLSM
Now FHWA wants us to keep on Going and Going
Get Your Hands Dirty - It’s Fun
Be Part of a Winning Team! (Students Working on Federal Funded CLSM Research)
Transportation Materials & Geotechnical
It’s Fun
It’s Changing the World
Is it the most important part of Civil & Environmental Engineering?
Obviously (and that’s an unbiased opinion)
Just try constructing something without materials!
