  • Abstract:
    The tremendous highway improvement program now underway in the United States has sparked the development of many new methods and techniques for engineering and construction. Their range has been diverse, but all have had common objectives: The most effective use of manpower, materials, machinery, and money. Some of the developments have been novel, even spectacular new applications of photogrammetry, automatic guidance of roadbuilding machines, nuclear testing, and use of the electronic computer, for example. But there are other, less dramatic approaches toward the stated objectives that can be equally significant and equally productive of efficiency and economy. Among these lies an especially fertile field-simplification, standardization, and uniformity, within reason, of design practices and construction specifications. Within this broad area, aggregate gradation specifications seem particularly susceptible to improvement. It was with this objective that the Bureau of Public Roads undertook the analytical study reported in the first article in this pamphlet. It merits the careful consideration of all roadbuilding agencies and, it is hoped, prompt attention along the lines of the recommended course of action. Because it is closely related to the objective of improving aggregate gradations, there is included in this pamphlet an article on the development and use of the new Public Roads graphical chart for evaluating aggregate gradations.
