Three Year Results on the Performance of Incinerator Residue in a Bituminous Base.

摘要

The use of incinerator residue as an aggregate in a bituminous base (termed littercrete) was studied. Test sections consisting of the experimental hot mixed littercrete base and a conventional hot mixed asphaltic concrete base (termed blackbase control) and topped with a conventional surface were placed on a city street in Houston,Texas. This report presents the results from observations and tests on cores during the first three years of in service performance. Results of the laboratory and field evaluations show that the littercrete section is performing in an excellent manner,almost identical with the conventional blackbase control section. The only distress that has occurred is minor cracking in both sections. This cracking is limited to the conventional wearing surface and has not progressed into the bases.
