Abstract

Abstract: Expansive soils are widely distributed and the losses induced by the expansive soil hazards are significant. This paper presents a case study of using the weak expansive soil from the foundation excavation waste as the controlled backfill material. Throughout the on-site trial and backfill tests, a cost effective solution of utilizing the waste soil is proposed.

Key words: Expansive Soils, Backfill Materials, Risk Control, Trial Tests, Air Dried Soils
