Title:

Leaching of Copper and Zinc from Fly-Ash-Amended Highway Base Layers

Accession Number:

01341190

Record Type:

Component

Abstract:

A study was conducted to evaluate the leaching potential of unpaved road materials mixed with lime activated high carbon fly, and to evaluate the potential groundwater impacts of leaching of zinc and copper. This objective was met by a combination of batch water leach tests, and computer modeling using WiscLEACH. The results indicated that an increase in lime kiln dust (LKD) and fly ash contents have significant effects on leaching behavior of heavy metals from soil-fly ash mixture. An increase in fly ash content and a decrease in LKD content promoted leaching of copper whereas zinc leaching was primarily affected by the fly ash content. Furthermore, WiscLEACH provided valuable prediction about the leaching pattern of the two metals in a highway environment.
