HIGHWAY CONSTRUCTION USAGE FACTORS FOR AGGREGATES
In an effort to aid commercial pit and quarry operators as well as highway contractors, engineers and economists in plannning highway construction programs, tables are presented of usage factors for aggregates. Aggregates constitute between 20 and 30 percent of the cost of all materials and supplies and between 9 and 13 percent of the total construction cost (excluding the cost of right-of-way and engineering). The data employed in the development of the factors are quantities od the major materials used and the factors are quantities of the major materials used and construction projects on the Federal-aid Primary System. The factors are quotients obtained when total quantities are divided by corresponding totals in millons of dollars of final construction costs. These factors may be applied to any program of highway construction expenditures to obtain estimated requirements. Percentage distribution of cost for aggregate are tabulated, as well as the estimated construction expenditures for all public highways. Estimated national average secondary road factors are also presented.
