Trr No. 1260 Pavement Design, Management And Performance., pp. 166-179 This paper has presented a microcomputer program for back-calculating the moduli of a pavement structure using deflection basin data. The solution techniques for use in developing the program are described, including use of the method of equivalent thicknesses, Bousinesq theory, consideration of non linearity of pavement ma…

This paper presents a comparison of pavement layer moduli determined from backcalculation with those measured in the laboratory on asphalt concrete (AC) and granular base materials. Deflection data and pavement materials obtained from two conventional flexible pavement structures were used. Pavement surface deflections were measured with a Falling Weight Deflectometer and were used in backcalcu…
