Abstract

The oxygen diffusion coefficients of compacted Asphalt Concrete (AC) mixtures are an important parameter that indicates the mixtures’ aging susceptibility as well as their capacity of facilitating oxygen flow in asphalt pavements. Recently, a set of equipment and procedures have been developed to test the oxygen diffusion coefficients. The laboratory test procedure, however, is time-consuming for some asphalt mixtures with low diffusion coefficients. This paper reports the effects of timing the labora-tory-determined oxygen diffusion coefficients of compacted asphalt mixtures. It is anticipated that findings can help more efficiently determine the oxygen diffusion coefficients of compacted asphalt mixtures.
