PROBLEM TO BE SOLVED: To provide a base isolation rubber laminate in which hard plates having rigidity such as metal plates and rubber layers are laminated alternately, whereby it is possible to give a high damping characteristic for base isolation supporting, a less temperature dependency of the elastic characteristics, and the excellent processability of a rubber composition to form the rubber layers. SOLUTION: The base isolation rubber laminate 10 is configured so that hard plates 14 having rigidity and rubber layers 16 are laminated alternately, wherein each rubber layer 16 is composed of a rubber composition containing at least one of asphalts, tars and pitches in 1-70 pts.wt. relative to 100 pts.wt. of a rubber material and further 1-35 pts.wt. polyolefin wax is added thereto. |
