More Effective Cold, Wet-Weather Patching Materials for Asphalt Pavements
To the motoring public, potholes are one of the most visible and annoying forms of pavement distress. The overall objective of the project was to develop and test improved cold-mix, stockpiled patching mixtures. To satisfy the objective, the predominant failure mechanisms and concomitant performance requirements were established. Binder performance was identified as the most promising area of study. More than 40 experimental binders were evaluated in the laboratory, and five of these binders were chosen for field trials. It was found that current mix designs for cold-mix, stockpiled patching materials were inadequate, and, therefore, a new mix design procedure was adopted for use in the study. Field trials were conducted, in which 410 repairs were made and were monitored over a 1-year period. Mixtures employing certain high-float medium-set emulsion binders performed demonstrably better than companion control mixtures.
