Mechanistic Evaluation of Fly Ash Asphalt Concrete Mixtures
Publication: Journal of Materials in Civil Engineering
Volume 8, Issue 1
Abstract
This investigation was carried out: (1) to study the effect of fly ash on the mechanical properties of asphalt mixtures; and (2) to evaluate the effect of using fly ash in mitigating pavement distress and improving performance of asphalt concrete pavement. In this study, four groups of specimens with various fly ash contents were studied. The mechanical properties (resilient modulus, creep, permanent deformation, and fatigue) were determined at three different temperatures. Moisture damage tests were carried out. The VESYS model was used to predict pavement performance. Results from this study indicated that fly ash can be used as a mineral filler to improve resilient modulus characteristics and stripping resistance. The addition of fly ash did not significantly reduce field performance of asphalt concrete mix in terms of rut depth and present serviceability index but increase the amount of surface cracking in the pavement.
