Abstract
Trestle is a connecting bridge between the mainland and jetty, located in tidal areas with a high risk of corrosion and concrete deterioration. Generally, trestle structure construct for reinforced concrete and steel structure, which are particularly vulnerable to damage due to corrosive environment. As one of the major port support facilities to accelerate economic growth and distribution for industrial and agricultural products, it is necessary to have regular evaluation and maintenance.
Biringkassi port which belongs to PT. Semen Tonasa has been operating since 1988, and it is continuously adding facilities to support the cement distribution by sea. This study aims to assess the level of concrete deterioration and evaluate the capacity of trestle structures, which heavy vehicles pass at all times.
Results of concrete quality evaluation with ultrasonic pulse velocity and core drill concrete showed satisfactory results with the average quality of concrete over the 30 N/mm2. However, from the structural capacity review to the service load, it is necessary to limit the maximum load and repair the existing concrete deterioration.
