ASPHALT HARDENING AS AFFECTED BY FILM THICKNESS, VOIDS AND PERMEABILITY IN ASPHALTIC MIXTURES

A laboratory study was conducted to examine the influence of asphalt film thickness, voids and permeability on asphalt hardening in asphalt mixtures. Accordingly, some graded mixtures used in Indiana and some single-size mixtures were selected for the study. Values for permeability, voids and asphalt film thickness were obtained for the compacted specimens. The specimens were then subjected to accelerated oxidation. In this study a non-destructive compressive creep test was used on the asphaltic mixture.
