Partial bond A new technique for the construction of composite bridges (AGB2001/488)
Overview
Background & policy context:
A new technique is presented in bridge composite, the part of the adhesive bond. Prefabricated plate segments on the steel beams are relocated; these stick together to harness and then establish the bond between the produced slab and the underlying steel beam. The preparation of this compound is accomplished by a cement grout injection into a volume-optimized gap between the two.
The design of these joints, their grouting with the injection material, its capacity to boost power transmission and to determine the required bias for overprinting of adhesive joints between the plate segments are the subject of investigations summarized in this project.
Objectives:
The construction method for precast segmental deck slabs - partial bond.
Optimise method of construction. In particular the injection of the joint with the cement grout (erection of steel girdler, deck segments, gluing of the segments, longitudinal prestressing of the deck, injection of the sealing rubber hose, wetting of the composite joint surface, injection of the composite joint, wearing surface).
Methodology:
A. State of the art report
B. Application for composite bridges
C. Analysis of problems
D. Recommendation for construction
