Abstract:
For a variety of reasons, one should anticipate that the performance specifications for expansion joints will become increasingly stringent. This paper attempts to consider the design implications of such specifications. The following desirable features and practical means of achieving them are discussed: i) continuous seals that can accommodate severe directional changes at curbs and walls, ii) fully radiused directional changes of the metal and polymeric components, iii) simple replacement procedures, and the ability to accommodate modifications for overlays, iv) fasteners which do not rely on friction to prevent impact or vibration induced slippage between components, and v) no reliance on adhesives for bond between the seal and metal components.
