The Small Scale Seal Performance Tests (SSSPT) were a series of in situ tests designed to evaluate the feasibility of various materials for sealing purposes. Testing was initiated in 1985 and concluded in 1995. Materials selected for the SSSPT included salt-saturated concrete, a 50%/50% mixture of crushed salt and bentonite, bentonite, and crushed salt. This paper presents a summary of the SSSPT field program, results of the in situ testing, and a discussion of post-testing laboratory studies of salt-saturated concrete. Results of the SSSPT support the use of salt-saturated concrete, compacted bentonite clay, and compacted crushed salt as sealing materials for the WIPP.
