Laboratory Tests for Granular Materials for Flexible Airfield Pavements

The U.S. Army Engineer Research and Development Center (ERDC) conducted a series of full-scale traffic experiments on flexible pavement test sections to evaluate design criteria for military pavements. The experimental research objectives were to evaluate the minimum thickness of asphalt surfacing for the F-15 and C-17 aircrafts, evaluate the performance of marginal base materials in flexible pavements, and evaluate the newly developed thickness criteria for flexible pavements. Standard triaxial and repeated-load triaxial tests were conducted on the 5 granular materials used in the test sections. These tests were also conducted on CH subgrade clay having California Bearing Ratio (CBR) values of 4, 10, and 15. By closely following the protocol described in the National Cooperative Highway Research Program Report 453 for the development of laboratory test procedures for evaluating the quality of granular materials, ERDC developed test protocols to evaluate the resilient modulus and shear strength of the materials being tested. This paper presents the test protocols, example material test results, and a proposed procedure for analysis of the material test data.
