A deteriorated prestressed box beam was tested. The beam was a 23.3 m (76 ft 6 in.) long box section, 0.91 m (36 in.) wide and 0.84 m (33 in.) high with 127 mm (5 in.) thick walls. Originally, the beam had 18 13 mm (1/2 in.) diameter prestressing strands with each strand having an area of 99 sq mm (0.154 sq in.).
