Tables are presented of usage factors that are intended to aid mills, fabricators, annd related industries as well as highway contractors, engineers, and economists in planning to meet the needs of highway construction programs. The usage factors, in terms of units of the various materials per million dollars of construction cost when multiplied by the number of millions of dollars for either a Federal-aid or non-Federal-aid highway construction program, will result in reasonably accurate estimates of material requirements. Steel constitutes between 16 and 29 percent of the cost of all materials and supplies, and between 7 and 13 percent of the total construction cost (excluding the costs of right- of-way and engineering). The percentage distributions of costs for various steel classifications are presented, as well as the estimated construction expenditures for all public highways. The estimated national average secondary road factors are tabulated.
