The City of Casselberry has had experience using Warm Mix Asphalt (WMA) for road rehabilitation projects since 2013. They developed a mandatory WMA specification and have used it to resurface over 15 miles of roads. Contractors report that WMA has advantages like improved workability, especially in winter conditions. It also produces a nicer quality surface when used in thin lifts compared to hot mix asphalt. The city has observed WMA provides a quality surface at a reasonable cost and estimates carbon dioxide savings. However, the long term longevity benefits compared to hot mix asphalt have yet to be determined.
