In 2011 alone, recycling America's roads saved about 21.2 million barrels of liquid asphalt binder worth some $2.2 billion.
According to a survey conducted by the National Asphalt Pavement Association (NAPA) under contract to the Federal Highway Administration (FHWA), record-high levels of recycled materials were used in the construction of new pavements and the use of energy-saving warm-mix asphalt also reached a new high during the 2011 construction season.
