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 (NDT) equipment for district testing, including falling-weight deflectometers (FWD) and a skid truck and trailer for friction testing.
