Sažetak
The paper presents the reconstruction of the damaged reinforced concrete bridge with high performance concrete modified with styrene-butadiene latex and fiber reinforcement. After 30 years in service the severe damages of concrete cover and reinforcement corrosion were observed. The detailed testing has shown poor quality of concrete, low strength and up to 25% reduction of certain number of reinforcing bars. The bridge reconstruction was executed with one layer concrete overlay 20 cm thick. The repair high performance concrete was designed for the following properties and purposes: - to strengthen the span structure by increasing the depth of cross section by 10 cm replacing partly the damaged concrete, insulating layer and asphalt overlay, - satisfactory resistance to freezing and deicing chemicals, - resistance to wear and abrasion, - to serve as the impermeable overlay replacing the insulation.
