Abstract
An expansion device for deformation joints, a pavement structure and a construction method thereof. The device is installed above the deformation joint in a groove and consists of: a displacement support plate fixed above the joint; an elastic support component with fixed bases on two sides of the displacement plate and a rigid telescopic member, which is suspended above the joint and provides elasticity along the connecting line of the bases; and an elastic body that fills the groove and covers the support component. By introducing steel components into the elastic body, the device improves structural strength, integrity, and driving comfort of a pavement.
