Abstract


The construction of the bridge serves to connect the broken road segment because of an obstacle (river, valley, or highway that is not crossing a plot). The structure of the bridge in Indonesia mostly uses a simple placement system structure which means the structure between the floor of the vehicle with the abutment of one another separated by joint. The joint is usually closed using a construction called expansion joint. Some problems arising from the use of expansion joints such as the occurrence of cracks on the floor of the bridge vehicle, so that water can enter and cause corrosion on the beams and bridge placement. The use of link slab becomes an alternative solution to the problem. This planning was carried out on the reinforced concrete girder bridge type T beam spans 25 m x 2 in accordance with SNI No: 1748-1989-F Ministry of Public Works using the classical method introduced by Carner and Zia Year 1998. From the planning, obtained the overall length of link slab and the length of debonding zone is 3,8 m and 2,55 m respectively. The main reinforcement of link slab D19-350 mm while the temperature shrinkage reinforcement use D12-275 mm.
