The importance of carrying out bearing and expansion joint inspections by proficient and competent engineers who understand their functionality can often be key to maximising a structure’s lifespan and avoiding major, unexpected, emergency repair costs.
USL Ekspan have carried out a number of projects for swing bridges and foot bridges. From design, fabrication of all structural components, to trial erection and final installation. Details of these type of bridge installations can be supplied on request.
USL Ekspan offers three asphaltic plug joint systems, all in accordance with CD 357 standard for use on all classes of highway bridges.
FEBA - is a standard asphaltic plug joint which provides a flexible, waterproof joint with excellent ride quality for users and noiseless characteristics for minimal impact on the environment. Asphaltic plug joints are recognised as being suitable for a maximum design movement of +/-20mm horizontally and +/-1.5mm vertically and are ideal for use on bridges with low traffic volumes such as B roads.
FEBA HM - is a high modulus asphaltic plug joint suitable for low to medium movement of +/-20mm on heavily trafficked highway bridges. FEBA HM is a special blend of bitumen, polymers, fillers and a surface active agent, formulated to combine good fluidity at process temperatures with low temperature flexibility and ambient temperature slump control. The use of basalt aggregates (BS EN 13043) ensures excellent load bearing capacity and high resistance to wheel tracking. This amalgamation of a highly interlocking aggregate allows the system to provide excellent anti rutting characteristics.
FEBA HC - A bituminious asphaltic plug joint which has been developed for use in Tropical Climates.
NOTE: Design, construction and installation criteria remain the same for all joint types.
