    Abstract

    Results of an experimental program are presented for the interface friction mobilized between expanded shale lightweight aggregate and commonly used structural materials: formed concrete, steel, and wood. A large-size direct shear device is used to perform tests. The mobilized friction between lightweight aggregate and solid surfaces of construction materials are compared with interface angles of friction associated with coarse normal-weight aggregates. The results provide useful design information on the appropriate mobilized angle of friction to be used while designing retaining structures with lightweight aggregate as backfill. The data are also useful in estimation of skin friction for piles driven through lightweight aggregate fills.
