Abstract
La présente invention concerne un tablier de pont (10) de masse réduite où une pluralité de zones vides de béton permettent une moindre force de poids mort et une réduction du coût du produit. Le tablier de pont (10) est constitué d'une structure de barres support (16), de gaines de post-tension (20) et de modules de béton (18). Chaque module de béton (18) est pourvu de saillants (28) espacés les uns des autres et tournés vers le bas. Ces saillants servent à distribuer latéralement les forces de façon à pouvoir réserver des zones (17) vides de béton entre les saillants. Les gaines de post-tension (20) traversent et occupent l'intérieur des saillants (28) tournés vers le bas. La résistance du tablier résulte de la mise en place, à l'intérieur des gaines (20), de câbles de précontrainte (42) tendus et ancrés aux extrémités du tablier de façon à exercer une précontrainte sur le module de béton (18).
