USE OF POWER PLANT AGGREGATE IN ASPHALTIC CONCRETE

The term power plant aggregate is used to identify the ash that is collected at the bottom of the furnace in cold burning power plants. The paper discusses the material, laboratory evaluations of it, mixture design, physical and mechanical properties. Among the conclusions reached are that each specific use requires a separate mixture design and evaluation as with any conventional aggregates. In order to be utilized, the power plant aggregate must be economically and technically equivalent to the aggregate it is replacing. It must not cause the contractor undue inconvenience, such as the uncertainty of supply, increased handling, etc.
