PURPOSE: An anti-expansion joint bridge is provided to enable a vehicle to easily travel the bridge and to prevent noise and frictional force when the vehicle is traveled. CONSTITUTION: An anti-expansion joint bridge comprises a pair of upper plates(100,100'), multiple sliding plates(200), and asphalt concrete(300). The upper plates are separated from each other and are expanded and contracted depending on a temperature change and a load. The sliding plates are formed on the top of the upper plates and cover a separated part between the upper plates. The asphalt concrete covers the sliding plates. |
