Abstract

The purpose of this study was to research on compressibility characteristics of waste tire powder-added lightweight soil(TLS) for recycling dredged soil, bottom ash and waste tire. The TLS used in this experiment consists of dredged soil, cement, waste tire powder and bottom ash. Test specimens were prepared with various content of waste tire powder ranged from 0% to 100% at 25% intervals by the dried weight of dredged soil. Several series of one-dimensional consolidation tests were carried out. Based on the experimental results, as the waste tire powder increased, the swelling index of TLS increased. The compression index and swelling index of the TLS with bottom ash content showed lower value than without bottom ash. Then, compressibility characteristics of TLS were strongly influenced by mixing conditions of waste tire powder content and bottom ash content.
