The Magic of Rubberized Asphalt

The use of recycled tire rubber in asphalt is increasing. Transportation agencies in several states have specifications for adding recycled tire rubber to asphalt binder. Prices for asphalt cement and polymer is rising, while the price for recycled tire rubber remains steady. Rubber contains polymer and oil, making it an economically advantageous asphalt extender. The recycled tire rubber can be added to asphalt in several ways. The classic method is a wet process, adding rubber at nearly twenty percent by the weight of the liquid asphalt cement. Another method involves blending rubber at an asphalt terminal or in the field. A third method is a dry process, using very finely ground rubber. The various methods are being implemented around the country.
