Abstract

The use of waste tyres can make the ground improvement project cost-effective, and moreover, this can be a solution to the tyre disposal problem. A series of standard compaction and unconfined compression tests was conducted to investigate the effects of adding tyre fibres (TFs) and cement on the engineering behaviour of Perth sandy soil. The contents were varied from 0% to 3% of dry soil by weight for both cement and TF. The cemented specimens were cured for 7 days. The compaction tests results indicate that the maximum dry unit weight generally increases with addition of cement but decreases by TF inclusion, while adding cement and TF results in a lower optimum water content. The results of unconfined compression tests show that the cement addition increases the unconfined compressive strength (UCS) of the sand and sand–TF mixtures. Furthermore, the inclusion of TF in the sand increases its UCS, whereas UCS of the sand–cement mixtures mostly decreases with an increase in TF content, except for a slight improvement at low cement contents.
