An elastomeric bearing pad is a device constructed partially or wholly from elastomer,
51
52
53
the purpose of which is to transmit loads and accommodate movements between
54
55
56
bridge and its supporting structure. Reinforced bearing consists of alternate layers
57
58
59
of steel or fabric reinforcement and elastomer, bonded together.
