A 24-foot (7.32-meter) farm-to-market road, heavily traveled by trucks, was reconstructed using the old asphalt surfacing as aggregate in the lime stabilization of the subbase. After tearing up the old surface, the material removed was broken up and then pulverized to 2.5 in. (6.35 cm) or less. The clay subbase was then mixed with the pulverized asphalt and spread with lime. Following further mixing, the calculated quantity of water was added and the material was left to stand overnight. The following day the clay, lime and asphalt aggregate were mixed well to a depth of 10 in. (25.4 cm) and compacted. An asphalt surface 2 in. (5.08 cm) thick was put down. The work was done on one lane at a time, since the road had to remain open to traffic. Cost savings resulted from the recycling process, since the salvaging of some 16,000 yards (14,560 meters) of waste material eliminated the need to purchase and bring in approximately 33,000 tons (20,000,000 kg) of crushed stone.
