CON-SERV provides neoprene and natural rubber Elastomeric Bearing Pads to provide structural support in bridges, as well as in commercial and industrial buildings, and petrochemical and power plants. These parts, depending on the type of elastomer, provide uniform load transfer, accommodate thermal movement, allow for end-beam rotation and isolate components of the structure against vibration, noise and shock. CONSERV produces both AASHTO-grade neoprene and AASHTO-grade preformed fabric pads. These can also be supplied with filled PTFE bonded to them for use as the lower element in a slide bearing, which will provide both the longitudinal movement and 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-gauge steel laminate which has 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.
