New York City’s Department of Transportation has begun using more environmentally friendly and versatile road-repaving methods. The city has begun implementing the use of warm-mix asphalt that only needs to be heated to 200 degrees Fahrenheit – as opposed to traditional asphalt’s required 300-325 degrees needed for previous resurfacing operations. NY1 reports that the warm-mix asphalt’s lower temperature requirement allows roads to be paved with two-thirds less energy. The warm-mix asphalt can also be used in cooler weather, potentially providing quicker DOT response times for road problems caused by cold weather. The DOT is currently monitoring the progress of two roads resurfaced with the warm-mix – one repaved during the summer and the other during the winter. A year after the city resurfaces two more roads this season, officials will evaluate the condition of the roads and determine if the mix can be used as a standard.
