BEJ Expansion Joint
PRODUCT OVERVIEW
The ‘'BEJ’' expansion joint is a surface mounted mechanical system, with an elastomeric insert between two metal runners or carrier rails. It is unique in that the rails which house the insert are set into a rapid curing elastomeric resin compound known as Britflex Resin Mortar.
The ’BEJ’ system is registered with the UK Highways Agency for use on highway bridge decks on all classes of roads and motorways. (Department of Transport BD 33/94: Joint Type 6 refers). The ’BEJ’ system is included in the Highways Agency list of approved products SA1. Britflex Resin Mortar is also included in SA1 as an approved transition strip material for types 5 and 7 expansion joints. ‘BEJ’ Expansion Joints incorporate cellular elastomeric inserts which are load bearing enabling a range of movement to be accommodated up to 150mm.
The Britflex ‘BEJ’ is ideally suited for maintenance schemes to replace other failed joint systems. The on-site assembly for maintenance is rapid and the roads can be opened to traffic within about 2 hours for installation of new joint.
