Development of Design Guidelines for Use of Shredded Tires as a Lightweight Fill in Road Subgrade and Retaining Walls

摘要

The objective of this research was to identify one or more suitable methods for the utilization of shredded tires in road subgrades and as backfill in retaining walls. Emphasis was placed on investigating the physical and mechanical parameters of the shredded tires such as size, bulk unit weight, specific gravity, porosity, angle of repose, and compressibility coefficients. These parameters are used in the design of highways or in geotechnical construction.
