The objective of this study was to investigate the effects of spent polyethylene (PE) addition on the mechanical stability and leachability bituminized waste forms. The waste used for experiments was the actual sludge generated from an industrial plating factory and spent PE generated from an agricultural polyethylene film, respectively. The bitumen used in sample preparation is straight-run distillation bitumen, a paving asphalt. Bituminized waste forms with PE contents of 5 wt% or more resulted in maintaining dimensional and mechanical stability. The compressive strength and softening point of bituminized waste forms increase in proportion to the amount of spent PE. Moreover, the enhanced mechanical stability is possible to evaluate the bituminized waste forms exactly. The precise leach test cannot be performed because of the deformation of the bituminous specimen. Leach test revealed that the principal leaching mechanism of metals (Zn, Cr, Cu) from bituminized waste forms is diffusion. |
