The objectives of the research reported are (1) to develop a method for estimating the total equivalent 18,000-lb. single-axle loads to which each study test section has been subjected (2) to determine the traffic parameters that will best predict future loadings, and (3) to develop a procedure for estimating axle-load growth. A traffic study involving collection of vehicle weight, classification and volume data, for each of 50 widely distributed test sections, was conducted in 1964. Using these data, together with data from routine annual statewide truck weight studies, the total traffic loadings on each test section during each year of life are computed. In addition, correlations are made between equivalent 18,000-lb. single axle loads and (1) average daily traffic (2) heavy commercial average daily traffic and (3) total 4- and 5-axle vehicles. Computer programs are presented for (1) determining truck weight factors for each vehicle type and (2) calculating total annual traffic loadings on each test section. (Author)
