ABSTRACT:
A bridge deck panel support system and method for supporting precast bridge deck panels on a bridge girder. The bridge deck panel support system (10) comprises at least one grade bar support member (24) which is anchored to the bridge girder (14) with a grade bar support anchor (16) so as to extend upwardly from the bridge girder (14). At least one grade bar (28) for supporting one or more deck panels (12) is secured to the upper portion (26) of the grade bar support member (24), the grade bar (28) being selectively spaced from the girder (14) such that a grout receiving space (32) is defined between the grade bar (28) and the girder (14). The grout receiving space (32) is filed with non-shrink grout (34) such that the load of the deck panels (12) is transferred from the grade bar (28) to the grout (34). The method of the present invention includes the steps of securing the grade bar support member (24) to the girder (14), securing the grade bar (28) to the grade bar support member (24), and substantially filling the grout receiving space (32) with non-shrink grout (34).
