Elastic vibration buffering pad and ballast bed vibration damping pad

The utility model belongs to the technical field of road building materials, and particularly relates to an elastic vibration damping pad and a ballast bed vibration damping pad, the elastic vibration damping pad comprises a vibration damping pad body and a plurality of non-linear rigidity protrusions arranged on one side of the vibration damping pad body, the contact faces of the non-linear rigidity protrusions and the outside are arc-shaped, and the non-linear rigidity protrusions are arranged on the other side of the vibration damping pad body. The bottommost part is designed into a circular arc shape, and in the bearing process, the contact area with a base is gradually increased, so that the rigidity is gradually increased, obvious non-linear rigidity is provided, and a good non-linear rigidity vibration isolation effect is achieved; the ballast bed anti-vibration pad comprises the elastic vibration buffering pad and the composite pad layer arranged on one face of the elastic vibration buffering pad, and
