Neoprene bridge pads -- Fatigue behavior in compression and shear

Brielmaier, A.A. / Hoblitzell, Jr., J.R. / Borden, G.G.

Results of fatigue tests performed in temperature range from 0 to 120 F under compression and shearing loads are reported; though tearing, chafing, raveling, and separation of neoprene from metal shims in laminations were observed, damage occurred at shearing deflections higher than present design limit of plus or minus 25%; shearing stiffness increased markedly at 0 F, indicating that at low temperatures bridge supports may be subjected to appreciable horizontal forces; to prevent slippage at low temperatures, minimum vertical pressure of 250 psi is recommended for design shearing-deflection limit of plus or minus 25%.
