Abstract

A detailed laboratory investigation was undertaken to study the effects of different mix components on several engineering properties of open-graded asphalt mixtures. Among these properties of open-graded asphalt mixtures. Among these properties are density, air voids, Marshall stability and flow, resilient modulus, tensile strength, and permeability. Properties of the open-graded mixture were compared with those of dense-graded mixtures and open-graded cores obtained from a porous pavement experimental test section. The asphalt content and aggregate gradation influenced the density, air voids, Marshall stability, instantaneous and total resilient moduli, and coefficient of permeability of laboratory-prepared open-graded specimens. The tensile strength was not affected by either the asphalt content or the aggregate gradation at a significance level of 0.05. The resilient characteristics were found to be highly affected by temperature. Additional Study results are discussed.
