宿务-科尔多瓦连接高速公路是菲律宾正在进行的最大的基础设施项目之一。该项目由一条堤道、一座横跨宿雾海峡通航区的巨型斜拉桥、两座高架桥和四座低矮桥梁以及道路和人行道组成。
CCLEX项目旨在提供更好的交通设施，同时减少该地区的交通拥堵，并改善宿雾市内的连通性。它还旨在支持科尔多瓦的经济增长，因为高速公路将使该市成为岛屿旅游业的门户。
这座收费桥也被称为第三曼达维 - 麦克坦大桥，于 2017 年正式破土动工，预计于 2022 年竣工。

连接宿雾岛和麦丹岛的斜拉桥

建成后，宿务-科尔多瓦高速公路将通过科尔多瓦镇连接宿务大陆和麦丹岛。这座长 8.5 公里的收费桥设有两条车道，每天可容纳 40,000 辆汽车。主桥采用400米斜拉索主跨，通航净空60米，船舶可轻松通过高速公路。
高速公路的主桥将连接瓜达卢佩河和科尔多瓦的贝壳岛，而其巨大的高架桥将连接到通往麦克坦的堤道和公路网。

Dextra Bartec，宿雾-科尔多瓦大桥建设的加固解决方案

该大型项目的设计和施工由宿务联线合资企业（CLJV）承担。 CLJV 是西班牙 Acciona Construccion SA 与菲律宾 First Balfour Inc. 和 DM Consunji Inc. 之间的合资企业。
为了加固这条巨型高速公路的地基，承包商选择了 Dextra 著名的钢筋拼接解决方案 Bartec。截至 2018 年 7 月，超过 35,000 个 75 级钢的标准、桥接和过渡接头（直径为 40 和 50）已应用于基础的桩笼。此外，为了在拥挤区域提供更好的端部锚固，CLJV 选择了 Dextra Bartec 头锚杆，也称为端锚。 Bartec 端锚是传统上用于锚固的钩杆的便捷替代品。

巴尔-博尔贾雷公路项目是黑山交通与海事部牵头的重点基础设施项目。它旨在改善国内以及黑山与欧洲其他国家之间的联系，以促进该国的经济和旅游业。

该项目由中国路桥公司承建，是中国与东欧合作的又一个成功典范。新的2×2公路全长超过40公里。它建在具有挑战性的地形上，但满足欧盟和黑山的道路基础设施标准。它的时间表也雄心勃勃：道路和高架桥都应在 4 年内建成。

对于 Bar-Boljare 高速公路项目，Dextra 提供了 Bartec 钢筋连接器解决方案，在四个高架桥的桩中使用了钢筋拼接。该项目选择 Dextra Bartec 拼接解决方案是因为它符合 ISO 15835 S2 标准，该标准定义了钢筋连接器和钢筋能够抵抗剧烈地震条件。已向中国路桥供应了总计23万个Bartec钢筋连接器。

圣雄甘地塞图（也称为甘地塞图或恒河塞图）是一座横跨印度比哈尔邦恒河的桥梁，连接巴特那和哈吉普尔。它是印度第三长的河桥，长5,750米。

近几十年来，由于通过桥梁的汽车数量增加，这座桥经历了严重的交通拥堵，导致桥梁超负荷运行，结构负担过重。它需要用钢框架替换混凝土上部结构。

Dextra 参与了这一改造项目，提供 RepairGrip 连接器用于连接旧桥墩和新桥墩盖。

在拆除旧上部结构时，还提供了全螺纹钢筋以供各种应用。

翻新后的西侧于2020年7月31日向公众开放。

The Cross Tay Link Road project in Perth and Kinross, Scotland, is set to transform transportation in the area. One of the notable features of this road construction endeavor is the inclusion of a three-span bridge over the magnificent River Tay, the longest river in Scotland. This project aims to enhance connectivity and improve travel efficiency for residents and visitors alike.

To ensure the structural integrity of the bridge’s foundation piles, Dextra provided a quantity of 1,920 tubes, amounting to 11,136 linear meters of Sonitec ST50. This specialized product is designed for pile integrity testing using the Crosshole Sonic Logging (CSL) method. It facilitates the evaluation of the quality and reliability of the foundation piles, ensuring the bridge’s long-term stability and safety.

The Tan Vu – Lach Huyen Bridge is a 5.4-km long bridge located East of Hai Phong, in the North of Vietnam. The brige is connecting the Hai Han district (East of Hai Phong), to the new port of Lach Huyen, located on the island district of Cat Hai. This will also allow the port of Lach Huyen to be directly connected to the Hai Phong/Hanoi highway, drastically reducing the transit time to Vietnam’s capital city.

The bridge project is part of a broader infrastucture plan: the Tan Vu – Lach Huyen highway infrastructure project, which aims to develop Hai Phon as a main transportation hub in the North of Vietnam.

For this bridge project, Dextra supplied two types of 后张法 systems:

• For the permanent reinforcement of precast girder segments, Dextra supplied PT smooth bar systems with threaded ends in sizes M39 and M49, grade 835/1030 and 930/1080. Dextra bar systems are used for the vertical post-tensioning of concrete segments.
• For the lifting and temporary fixing of the precast girders segments during the construction phase, Dextra supplied its Fully threaded bar systems in diameters 32 and 36, grade 1080/1230.

For all temporary applications such as lifting and fixing operations, Fully threaded PT bar systems are a convenient and economical solution as they bars can easily be cut, adjusted and re-used several times. Thanks to their continuous thread, the bars can be spliced at any points by the use of couplers or turnbuckles, which are also available from Dextra.

The replacement of the Smith River Bridge at the South Fork Road, Crescent City (also named George Tryon Bridge) is a local infrastructure project initiated by the Federal Highway Administration (FHWA) and handed over contractor Flatiron West, Inc. The aim of the project is to replace an existing steel bridge, built in 1948.

For this project, Dextra supplied its Bartec rebar coupler solution. Bartec allows a convenient connection of rebars on large diameters from #4 to #18 (Imperial rebar sizes) and were used in columns and beams of the new replacement bridge. Bartec takes advantage of extended threads on rebars to splice them without the need of rotating any bar and without any extra further component: only a standard rebar coupler is required.

Additionally, Bartec Headed Bars were also supplied, replacing hook bars in congested reinforcement areas.

Bartec is a prequalified and authorized solution by CALTRANS (California Transportation Department) and has previously been tested and approved by the California Department of Transportation.

The Bach Dang Bridge is the first all-Vietnamese designed and constructed mega infrastructural project located in northern Vietnam. The project is estimated to cost 7.3 trillion VND (approximately 312.2 million USD). The bridge 5.4-kilometer bridge spans over the historic Bach Dang River and is part of the Hanoi – Quang Ninh highway project. It also features 4 lanes of 28 meters wide, meticulously designed for speeds of up to 100km/hour traffic. The bridge and highway connection are intended to help shorten the distance from Hanoi and Quang Ninh from 175 km. to 125 km., as well as to cut travel times between the two localities in half.

The construction of the first multi-span cable-stayed bridge in Vietnam

The very first made-in-Vietnam multi-span cabled-stayed bridge features 3 H-pylons, representing Hanoi, Hai Phong, and Quang Ninh urban areas. These regions are now connected by the bridge to boost their economic growth. Bach Dang River has a historical significance as it is the site of the Battle of Bach Dang in 938CE, where rebel Vietnamese forces defeated and put an end to the Chinese imperial domination of Vietnam. Bach dang Bridge will only enhance further the strategic edge of the northern region.

用于桥梁永久应用的 Dextra 后张拉杆

For the construction of the Bach Dang Bridge, Dextra fully-threaded bars were applied to it as permanent post-tensioning anchors.
For this mega infrastructural project, Dextra supplied over 100 high performance post-tensioning bar systems. Also known as PT bars, they are specifically designed for post-tensioned applications. They can be corrosion-protected as is the case for the equipment supplied in the project. The corrosion protection is done in a controlled facility in Dextra’s factory, before being shipped to site.
