The Bar-Boljare Highway is a key infrastructure project in Montenegro led by the Ministry of Transportation and Maritime Affairs and built by China Road and Bridge Corporation (CRBC). The 2×2 lanes highway spans over 40km, in seismic environment.
iNGEROP, the consulting firm on the project, required the rebar couplers to comply with ISO 15835 requirements (cyclic requirements as per class S2). For that reason, CRBC chose Dextra Bartec® solution for reinforcement connection.
Four large diameter soft eyes have been installed in the diaphragm wall cages of the new Singapore MRT Marine Terrace Station during August 2017.
Los Soft-Eyes están hechos de barras de refuerzo de GFRP, que se utilizan para sustituir el refuerzo de acero en las paredes D de los pozos de construcción. Cuando la tuneladora (TBM) atraviesa las paredes D, corta fácilmente las barras de GFRP, lo que ahorra tiempo en el cronograma del proyecto y dinero en el uso del equipo.
Dextra ha sido el pionero de esta aplicación desde su primer uso en el proyecto del metro de Bangkok en 1998 y tiene una amplia experiencia en el diseño y fabricación internos de Soft-Eyes.
The D-Walls installed on Terrace Station also feature Bartec® rebar couplers, a common application which allows for the horizontal re-connection of the station slabs.

Marine Tie Rod solutions can seem at start overwhelming at first as there are many many types of quay walls, anchorage types and ways to connect them with tie rods.
To guide designers through the creation of the perfect quay structure, Dextra has developped a comprehensive step-by-step palette of AutoCAD tool to be used in complement of our Marine Tie Rods Technical Guide. This new tool features our complete range of diameters, grades and accessories.
We hope that this new AutoCAD tool will speed up both understanding of our systems and the design of your structure. For all questions, Dextra Bar Systems dedicated engineering team remains available to support you in the system selection and drawing.

Postensado Bar systems are highly customizable and versatile solutions allowing for multiple applications in bridge/viaduct construction.
Dextra has recently supplied customized PT bar systems for the reinforcement of precast girder segments used on the Bang Pa In – Saraburi – Nakhon Ratchasima highway in the North-East of Bangkok.
 |  |
El Sistemas de barras postensadas, made of hot rolled deformed high-tensile bars (FT bars) Ø36mm, allow for the vertical reinforcement of the precast segments, with up to 14 sets per girder element.
Each bar will be jacked and put under the required tension from the top of each element while on the ground. After that the girder is lifted and installed in its final position.
Permanent corrosion protection will be achieved by filling a galvanized duct around the bar with grout.
Dextra recently released an update of all its rebar coupler tools to upgrade to latest version of Tekla.
New Tekla version now allows clear visualization of threaded bar ends, allowing to see the extended threads for first phase rebar for example.
Tekla attributes are available to download from Dextra website.
