In this research project an estimation is made of the environmental implications when primary materials (natural materials) are replaced by secondary materials (waste materials) in road constructions and building materials. Moreover the results will be used in order to contribute to the normalization of the application of secondary materials. This report concerns the results of leaching experiments of secondary materials.202 pnl17uitlogenzware metalenstandaard uitloogtestReport2012-12-12
