Concrete pavement design procedures in the United States have also been influenced
by full-scale pavement research conducted by the Corps of Engineers and the
Navy. These agencies, as well as the FAA (earlier known as the CAA) and the PCA,
published design procedures reflecting pavement condition surveys that were made
to evaluate pavement performance with respect to the thickness design procedures
employed. The PCA conducted such a survey in the late 1940s in cooperation with the
CAA. The PCA performed additional surveys at civilian airports in 1962 and 1963 (19)
and at military airports in 1956, 1965, and 1966. During this period, the Corps of Engineers
monitored pavement performance at Air Force bases, and the Navy performed
pavement evaluation studies at Naval Air Stations in the United States and overseas.
