Carrying out civil engineering mandates
Eurovia undertakes joint sealing of the Grande Ravine viaduct at Reunion Island
In conjunction with about ten companies from the VINCI Group, Eurovia took part in the construction of route des Tamarins, which was opened to traffic in June 2009. The road was designed to relieve congestion in the western part of Reunion Island. The project, launched in 2005, included the construction of a 33.7-km-long, dual 2-lane expressway from Saint-Paul to Étang Salé.
A team of specialists in joint sealing from Eurovia's Aubervilliers division was despatched to the worksite where it carried out over half of all joint sealing requirements for engineering structures, nearly 100,000 m2 in all. At the Grande Ravine viaduct, Eurovia used a new special formula developed at its research centre. The new product, known as Orthoplast® H, is the result of 18 months of research and testing. It was manufactured in France and shipped in heated containers.
Germany: Entry into service of a 24-km segment of motorway A4
A 24.5-km segment of the A4 motorway was officially opened to traffic. This segment consisting of a dual 3-lane configuration over 18.5 km and dual 2-lane over 6 km, is the Hörselberg bypass (located in central Germany).
The project required the construction of 3 connecting ramps, 3 viaducts, and 21 engineering structures as well as the installation of noise-attenuation barriers over a distance of 4,500 metres.
Work was launched in April 2008 as part of a design-build-upgrade contract for a 45-km section of the A4 motorway; the project is designed to relieve traffic congestion on one of the busiest east-west thoroughfares in Germany.
Hubbard: extending Maitland Boulevard in Orlando
Only minutes from downtown Orlando, Florida, teams from Hubbard Construction are building a 2.6-km expressway section. The section features a total of 925 m of bridge roadwork, including one 823-m bridge segment. The latter required installing 350 prestressed concrete beams, each weighing close to 78 tonnes.
Czech Republic: construction of a segment of highway R35
Lead contractor Eurovia CS completed work on the highway R35 project, which consisted of a 7.6-km segment in the Bily Kostel-Hradek nad Nisou sector in a region of the Czech Republic bordering on Germany and Poland. As part of the Prague-Liberec-Zittau (Germany) link, this dual 2-lane roadway segment called for 3 interchanges, 11 engineering structures, and 3 protective barriers. Highway R35 connects the highway networks of the three countries.
Upgrades to two bridges over highway A40 in Quebec
DJL is currently upgrading paved surfaces and two bridges that span the Maskinongé River at highway A40 west of the city of Trois-Rivières.
The project is designed to strengthen the bridges built in 1973.
...
Work is divided into three phases. Phase 1 consists in repairs to the structure of the south bridge. For phase 2, which focused on the demolition and reconstruction of the parapets, DJL used a 20-person team. Demolition of the concrete slab and parapets required several successive mechanical and manual steps, namely, the use of: a mechanical jaw; a hydraulic hammer mounted on a mini-excavator; and a jackhammer.
Another key requirement of the project was the replacement the bridge bearing structures, which allow the bridge to shift in accordance with climatic changes. DJL teams completed phase 3 with finishing work on the south bridge and its concrete slab, median barriers, and approaches.
