The report describes the development of a procedure that can be used to backcast and forecast estimated Equivalent Single Axleloads (ESAL's) for any particular segment of highway. A regression analysis was performed on annual ESAL's/1,000 vehicle for all the Interstate Highway and Parkways using AADT and YR(star)AADT as independent variables. The resulting equations permit calculation of estimated ESAL's for each year that a segment of highway has been in service. Total accumulated ESAL's also are calculated and presented for each highway segment. ESAL's for each highway segment for each year since 1971 are presented in APPENDICES C and D as strip maps.
