EVALUATION OF NAF EL CENTRO USING LAYERED THEORY.

Abstract

The techniques of the layered pavement method for the design of flexible pavements have been used to evaluate the flexible pavements at the U. S. Naval Air Facility, El Centro, California. This evaluation has provided in-situ moduli of elasticity for all components of the flexible pavements. The pavement surface course is composed of an asphaltic concrete having an average depth of 5.5 inches. The moduli of elasticity for this course varied from 308,000 to 382,000 psi. A sandy gravel was used for the base which had a mean depth of about 17.3 inches and a range in moduli values from 30,800 to 35,200 psi. The subgrade consisted of a fine-grained clayey silt or an inorganic clay of medium compressibility. The subgrade moduli varied from 6,000 to 14,000 psi. These analyses indicate that the burmister layered theory can be used to give a realistic indication of the load-deflection response of flexible pavements. (Author)
