COLD-MIX RECYCLING IN GEORGIA

The Georgia Department of Transportation (D.O.T.) has found that cold-mix recyclingis an efficient way of placing road widening and shoulder paving, as well as using up stockpiles of milled material. Although nearby stockpiles of millings were continuously used in hot-mix recycling, the Department needed to find new uses for grwoing stockpiles of milled material too far from the asphalt plant. The idea of using the stockpiles in a cold-mix became a reality when Georgia D.O.T. rented a pugmill and began experimenting with recycled millings. The first test was widening a 15-mile (24 km) stretch of state road by 2 feet (0.6 m) on each side prior to resurfacing. The recycled material consisted of millings with 1 1/2 to 3 percent CMS-2 emulsified asphalt added. The mixture was placed in a single lift to achieve a final thickness of 6 in. (150 mm). The experiment was so successful that the Department set up a plant using an available pugmill in Georgia's Cartersville District. Later, the Department purchased a new pugmill. Both mills were used to experiment with cold mixes for widening low-volume roads. (Author)
