Pavement Design

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.
