Polymer concrete underground utility structures are used to house outside plant equipment such as electrical distribution line splices, natural gas distribution vaults, water meters, and communication line splices. This test method provides procedures for full-scale testing of three loading conditions similar to vehicle loading that may be experienced in field installations. Results obtained may be used to determine the load-carrying capacity of the structure being tested and provide data for direct comparison between structures of various designs. While this method may be used for any underground structure, it is primarily for use on polymer concrete and polymer concrete/composite structures up to 10 x 10 x 10 ft (3 x 3 x 3 m) in size.
Keywords: handholes; polymer concrete; testing; underground structure; utility structure.
