INCINERATOR RESIDUE IN BITUMINOUS BASE CONSTRUCTION

The use of incinerator residue as an aggregate in a bituminous base pavement (tremed littercrete) was studied. Following a laboratory investigation a test section consisting of the experimental hot- mixed littercrete pavement, and a conventional hot-mixed asphaltic concrete pavement were placed on a city street in Houston, Texas. The two pavements were covered with a 1-1/2 in. (3.8 cm) wearing surface. Samples were taken of the loose mix. Cores were taken after compaction (before traffic), and cores were taken after six months in service. Results of laboratory and field evaluations show that the littercrete pavement meets current specifications for asphalt stabilized materials and littercrete can be constructed using conventional equipment and technology. The littercrete pavement is performing as well as the conventional blackbase control pavement. The estimated life of the pavement is 10 to 15 years (limited only by the subgrade). The high cost of aggregates in certain areas has made the use of the littercrete pavement economically feasible and there are some intangible benefits associated with the use of incinerator residue. /Author/
