    Abstract

    In recent years there has been a concerted effort by highway and airport engineers to develop methods of evaluating the supporting power of subgrades, base courses, and finished pavement designs by means of loading or bearing tests. From the investigations and testing programs of the various engineering organizations in charge of pavement design and construction, much has been learned about the technique of conducting loading tests and the interpretation of test results. In addition to the influence on load-test results of the strength characteristics of the subgrade soil, base materials, and paving materials, it is generally recognized that: (1) the size of bearing plate, (2) the magnitude of the load increments, (3) the terminal rate of plate movement for a given load increment, and (4) the sequence and arrangement of the load-test procedure itself have influence on the test results.
