PLACEMENT OF AN EXPERIMENTAL HOT-MIX RECYCLED PAVEMENT

A recycled bituminous concrete pavement was constructed on Route 4 in Burlington, Connecticut. This report describes the construction activities. The recycling of bituminous pavements can be satisfactorily accomplished using the heat-transfer method in stationary batch plants. Once the plant has been modified, it can be operated either in the conventional or recycle mode. Marshall structural properties, in-place densities of the recycled mixes and binder recovered from the recycled material paralleled results of tests on those of similar conventional mixes. Recycled mixtures were placed as surface, pre-mix base and structural overlay. In Connecticut, once a contractor is equipped to recycle at his plant, the cost to produce recycled mixtures would equal that of conventional mixes at todays asphalt cement prices. The energy consumed in producing and placing recycled mixtures is approximately thirteen percent less than conventional mixes. This recycling project of plus or minus 4,313 tons permitted a savings of the following materials: 1,294 tons of aggregate; 88.42 tons of asphalt cement and the equivalent of $3,570.00 of gasoline.
