MIXTURE PROPERTIES OF RECYCLED CENTRAL PLANT MATERIALS

The objectives of the research reported are to (a) define the material properties of central plant recycled mixes in Texas, (b) compare properties of these recycled mixes with conventional paving mixtures normally used in Texas, (c) evaluate the performance of the pavements containing central plant recycled mixes, and (d) compare performance of pavements constructed with recycled and conventional paving mixtures. Hveem, Marshall, resilient modulus, indirect tensile, direct tensile, and water sensitivity properties are reported for the recycled mixtures compacted both in the laboratory and under normal field procedures. Bituminous mixtures investigated include recycled asphalt concrete and recycled protland cement concrete. Performance is reported in terms of serviceability index as measured by a ride meter and by the use of a visual condition survey. The results of this study indicate that suitable bituminious mixtures can be produced by central plant recycling operations. Performance of pavements containing recycled mixtures appears to be suitable. (Authors)
