P.C. PAVEMENT RECYCLED

Composite paving with portland cement concrete (PCC) and asphaltic concrete aggregates in a seven-inch econocrete base course is described. The 1.4 mile project involves about 25,000 square yards of pavement and the processing of the existing pavement through two crushing operations to form the major ingredient of the "new" pavement. For most of this project only crushed PCC with varying amounts of concrete sand were used in the new concrete. This pavement was 9 inchs thick. The remaining 5,400 square yards of the project was a 11 in. thick monolithically placed composite section. The old pavement was broken, removed, transported to the plant site and crushed initially to a minus 6-inch size. On final crushing, the material passed the 1.5-inch screen. Problems related to crushing and removal are discussed, and mix designs are described. The project demonstrates that the recycling of PCC pavement is possible and feasible.
