31. 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! Enjoy the lab tours & contact us if we can be of assistance: L. K.
