In 1994 the pavement was milled and stockpiled at a nearby asphalt plant. The Asphalt-Rubber grindings were added to the virgin rock and oil so that the grindings composed 15% of the final mix. At another location, the grindings were put through a microwave process where nearly 100% of the output was composed of recycled Asphalt-Rubber.
To minimize the damage of pavement such as resistance to rutting and fatigue cracking, asphalt mixture modification is required. Virgin polymer offers the possibility of producing mixtures that can resist both rutting and cracking. Thus, using recycled polymer such as crumb rubber is a good alternative and inexpensive.
