The Leaching Behaviour of some Primary and Secondary Raw Materials Used in Pilot-Scale Road Bases
article
At TNO a two years lasting pilot-scale research was carried out into the leaching behaviour of some eight primary and secondary raw materials, used in road bases. Objective of the study was comparison of leaching characteristics between primary and secundary raw materials and verification of the suitability of standard leaching tests. The research was performed in test bins, measuring 1x2 meters, containing a sand layer, a foundation layer and an asphalt layer with grass verges. The materials that were investigated as a foundation layer were slags of municipal waste incineration, bottom ash, concrete destruction debris, lavalite, phosphorus slags, a mixture of blast-fürnace and steel slags, a fly ash-cement stabilization, a sand-cement stabilization, and sand. © 1991.
