Abstract: A joint structure for coupling adjacent precast concrete pavement slabs which is excellent in execution process for pavement, particularly is capable of ensuring the sliding of a reinforcing bar. A first horizontal hole for accommodating a reinforcing bar thereinto is provided at an end surface of the first precast concrete pavement slab. A second horizontal hole for inserting a distal end of the reinforcing bar is provided at an end surface of a second precast concrete pavement slab. Both horizontal holes have the same diameters, opposite in position to each other. A guide passage is defined through the second precast concrete pavement slab for its upper surface to communicate with its inner end surface. A hauling member is connected to a distal end of the reinforcing bar so that it may be inserted into the guide passage.
