Abstract
This invention is the concept and method of designing, fabricating in a factory environment and installing Deck Joint Systems (DJS) consisting of Ultra High Performance Concrete (UHPC) joint headers sandwiching the joint sealer and pre compressing the sealer using a plurality methods for applying compression. The deterioration of bridges due to the exposure to chlorides, most commonly from leaking joints, has been established as the biggest challenge for bridge owners in the US and abroad. In general, the lack of performance of deck joint systems constructed using state of the art practices is causing accelerated bridge deterioration, especially in areas where deicing chemicals are used.
Claims10
A process for designing and manufacturing a bridge deck joint system by attaching joint headers of a plurality of size, shape, and geometry to various types of bridge deck joint seals and mechanically induce precise predetermined precompression prior to installation.
