The volume describes six computer programs that are needed to implement the improved overlay design procedure developed for the state of Alaska. The programs are: ELSDEF, ELSCRN, BOUSDEF, AMOD, MECHOD, and ELSYM5. Each program is used for different purposes. Specifically, ESLDEF is used to determine pavement layer moduli from deflection basin data. ELSCRN is an auxiliary tool for use with the ELSDEF program and it makes ELSDEF much more easy and friendly. BOUSDEF is a backcalculation program. Like ELSDEF, the BOUSDEF determines pavement layer moduli using deflection basin data. BOUSDEF runs much faster than ELSDEF, therefore, it can be used for screening deflection data. AMOD is used to determine the modulus of asphalt concrete mixtures based on laboratory test data. MECHOD is a computerized procedure for mechanistic overlay design. Finally, ELSYM5 is a program used to calculate stresses, strains, deformation in a pavement using layered elastic theory.
