Summary:The utility model relates to a joint buffer pad for cement concrete pavements. The joint buffer pad comprises an upper-layer waterproof layer and a lower-layer elastic layer, wherein the waterproof layer is fixedly arranged on the elastic layer. The joint buffer pad is mainly used for buffering the damage to the pavements caused by the vehicle impact load effect at expansion joint and contraction joint parts of the cement concrete pavements, and meanwhile, pavement water can be prevented from directly permeating into a base layer and flushing the base layer, so the base layer can be protected, and in addition, cement paste can be prevented from permeating into the base layer during the concrete pavement construction.
