cold Recycling of Asphalt Pavements on Low-Volume RoadsThis road has many transverse, longitudinal, and reflected widening cracks. Many of these roads were widened in the past, and each time an overlay was applied, widening reflection cracks developed. Cold-mix re-cycling eliminates these cracks and provides a base with a uniform support across the entire width ofthe pavement. Roads
