Compositions and methods of utilizing recycled glass in backfill compositions

Abstract

Disclosed herein are compositions and methods relating to fine aggregate for a Controlled Low-Strength Material (CLSM) recycled from a consumer waste stream of bottle glass. Such disclosed compositions may be advantageous, for example, for backfilling trenches in street cuts for utility repairs or new utility installations, such as digital cables. The disclosed compositions that incorporate the recycled glass aggregate into a CLSM that achieves satisfactory compressive strengths. The disclosed compositions are not negatively impacted by Alkali-Silica Reactivity causing expansion.
