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. According to the invention, the distal end of the hauling member is drawn close so that the reinforcing bar can easily slide through the first horizontal hole toward the second horizontal hole.
