Rutting Performance of Cold-Applied Asphalt Repair Materials for Airfield Pavements

Cold-applied asphalt mixtures are often used for pavement repair, primarily because of the small quantities involved and/or the unavailability of hot-mixed asphalt. These cold-applied mixtures have poorer rutting resistance than hot mix asphalt because additives, often solvent, are required to provide adequate workability for them to be placed at ambient temperatures. This study primarily evaluated the rutting performance of nine commercial cold mix asphalt repair materials. Both laboratory wheel tracking data and field rutting performance were used in the evaluation with the focus on identifying suitable materials for repairing airfield pavements subjected to high-tire-pressure aircraft traffic. The commercial products included traditional cutback cold mixes as well as water-activated repair materials. Results from both laboratory and field rutting measurements showed that the water-activated materials outperform the products containing solvent. However, none of the commercial products achieved the target threshold of less than 1 in. rutting after 100 passes of simulated F-15E aircraft traffic. The laboratory wheel-tracking measurements proved to be a good indicator of field performance.
