Abstract:

A literature review was made to support an ongoing study to develop a method for evaluating airport pavements based on the layered elastic theory and using constants as determined from vibratory test results. The review covered the definitions and relations between elastic constants, methods used by various researchers for measuring elastic constants, and values of elastic constants found or used by various researchers. The review also included a study to determine the sensitivity of pavement responses to arbitrarily assigned values of elastic constants and an examination of the relationships between vibrator test results and elastic constants. The latter subject included a special preliminary examination of the relationship between the results from tests with the WES 16-kip vibrator and elastic constants. A summary discussion was given of the findings from the literature review and the special preliminary examination. Finally recommendations were made to facilitate further planning and implementation of the ongoing study mentioned. Author
