Project description:
A system of additional prestressing of a three-span road bridge with a standard load capacity and a total reinforcement weight of 8.8 tons was implemented. The system was a continuous single-beam structure made of monolithic prestressed concrete. The beam is prestressed by 7 unilaterally prestressed cables made of 18o Ls15.7 - 1860 and by 2 unilaterally prestressed cables 12o Ls15.7 - 1860. The cables were stored in steel protectors type LW 90 mm and 80 mm. The additional prestressing system is by BBV. After prestressing the structure, the cable ducts were grouted with cement mortar.
