Pavement Design


I-35, St. Louis Count Road 405

The Pavement Design Unit is one of the four Offices in the Pavement Engineering Section. We provide technical expertise on pavement design, determine timing of seasonal load restrictions, and administer the pavement-type selection process. We also maintain and operate Non-Destructive Testing equipment, including Falling Weight Deflectometers (FWD) for district testing and a skid truck and trailer used for friction testing.
