Abstract

Dynamic testing of aggregate bases D.-H. Chen, M. Zaman, J. Laguros School of Civil Engineering and Environmental Science, University of Oklahoma, Norman, CASL4 ABSTRACT The quality of pavement design is greatly dependent upon the accuracy and manner in which the material properties pavement are evaluated and used in the analysis. It has been estimated that approximately 95% of construction materials used in pavements are aggregates. However, traditionally, the testing and evaluation of their properties as pavement layers components have been conducted through static testing. In this study, six most commonly used aggregate bases in Oklahoma, U.S.A are tested employing dynamic loading, which simulates the repetitive nature of loading imposed by moving vehicles. The rectangular wave form is adopted to simulate the traffic load according to AASHTO designation T292-91I. The effect of moisture content, specimen, compaction method, gradation
