This specification covers preformed expansion joint fillers for use in concrete, brick, stone, and other paving and structural construction. The fillers are available in the following types: Type I, sponge rubber, which shall consist of preformed strips of a durable elastic sponge rubber compound using synthetic rubber or natural rubber as a base and containing no reclaim rubber or factice; Type II, cork, and Type III, self-expanding cork, which shall both consist of preformed strips that have been formed from clean granulated cork particles securely bound together by a synthetic resin of an incoluble nature; and Type IV, recycled PVC, which shall consist of preformed strips that have been extruded using scrap PVC material and using either no binder or a synthetic resin of an insoluble nature to securely bind it together. Materials shall be sampled suitably according to specified size and number, and shall meet property requirements as to recovery, compression, extrusion, expansion, boiling in hydrochloric acid, and density.
