ABSTRACT
Patching is one of the most common maintenance activities for potholes repair. If well designed and properly applied, cold mix asphalt can be considered a successful patching repair practice. It represents a short or medium-period solution able to minimize further pavement distresses, particularly in the case of low- to medium-volume traffic roads. In this context, the inclusion of bituminous roofing shingles could constitutes a good way to promote wastes recycling, satisfying actual increasing consciousness addressed to environmental sustainability and natural resources conservation. Given this background, the present paper shows a laboratory mechanical characterization of a cold asphalt mixture for patching repair manufactured with reclaimed bituminous shingles. Several empirical and performance-related properties were investigated at different testing conditions, specifically selected for such materials. Laboratory assessment showed that a properly designed cold asphalt including asphalt shingles seems able to guarantee enhanced performance, demonstrating promising application as patching repair for road maintenance activities.
