Abstract

The effects of different contents of foundry sand (FS), in a lateritic clayey soil (LG’) and a non-lateritic clayey soil (NG’) and the addition of 3% of hydrated lime, on the resilient modulus (MR) were investigated. The cyclic triaxial test was performed on the specimens after curing periods of 0, 7, 28 and 84 days. Five models were evaluated according to their precision to represent the MR. Environmental tests were also executed on soil sand and soil sand lime mixtures.  The results showed that the addition of FS reduced the modulus of LG’ mixes. Nevertheless, the mixes LG’ plus 20% of FS and NG’ plus 40% of FS and hydrated lime showed the highest results. Additionally, was observed that hydrated lime increased the MR, and this was more obvious at high curing periods. The environmental tests results indicate that FS reuse is not dangerous.
