In this study, use of foundry sand with some additives as a landfill cap layer material is examined. For this purpose, laboratory tests were performed with these samples: Foundry sand (For two different type of foundry sand: Green sand and Resin Bonded Sand), Foundry sand+ Bentonite (various proportions), Foundry Sand+Bentonite+Waste Rubber (Pulverized Rubber and Strip Rubber). Samples were compacted to their 95 % of o.m.c and dry density. The index properties, permeability k, split tensile strength, direct shear tests were carried out. It was found that increasing bentonite content (9 %) decreased the hydraulic conductivity below the requirements (1x10-9 m/s) for all foundry sand. Adding rubber (3%) to foundry sand bentonite mixture, increases the split tensile strength for all types of samples, but it also increased permeabilities. The results showed that green foundry sand with bentonite and waste rubber can be used as a landfill cap layer material.
