Deflection responses of a series of experimental test sections were obtained layer by layer during construction, upon completion of construction, and subsequent to construction. Deflections were obtained by use of Benkelman beams, the Road Rater, and the Dynaflect. Test results from one location within each test section were analyzed to determine which relationships were, or were not, meaningful. This was done as a pilot study and as a preliminary step toward final analysis of the data bank. The analyses are presented in this report.
