Abstract

When analyzing flexible pavements or predicting their behavior by such means as elastic-layered theory or by finite elements, it is necessary to know the parameters that govern the behavior of the pavement components. One of the most important factors to consider is the modulus of the asphalt bound layers.

In the past two decades, one method that has seen increasing use in the determination of the moduli of engineering materials (particularly soils) is the resonant column. However, its use in determining the moduli cf asphaltic concrete has not been widespread or well documented. In this study, which was part of a larger study on pavement rutting (1), attempts have been made to adapt the resonant column to testing asphaltic concrete. A brief summary of resonant column theory and a discussion of equipment, problems, and results are presented.
