CON-SERV Inc designs and produces both AASHTO grade neoprene pads as well as AASHTO grade preformed fabric pads. These pads can also be supplied with filled Teflon® (PTFE) bonded to them for use as the lower element in a slide bearing which will provide for longitudinal movement as well as the rotation required.
Plain and shimmed bearings are available in standard Shore A durometers of 50, 60 or 70 based on state and/or AASHTO Code, Section 18, natural rubber or neoprene. For economy, a commercial grade is also available.
PTFE surfaced neoprene backed slide bearings are also available. Type CSA material is recommended bonded to a 10 GA. steel laminate which has in turn been bonded to neoprene. If minimum dead load pressure is less than 200 psi, it is recommended that the elastomer be epoxy-bonded to concrete. If on steel, a tack plate is recommended for positive reinforcement. The maximum temperature at a neoprene bearing is 200°F.
