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 materialsl, and consideration of overburden pressure on stress calculation. Evaluation of the program was performed using two approaches : (a) comparing backcalculated moduli with hypotherized theoritical moduli, and (b) comparing backcalculated moduli with those from other developed backcalculation programs. The evaluation shows that the moduli backcalculated using the BOUSDEF program compare well with the theoritical moduli and also are compatible with other developed programs used for comparison.
