Bridge Projects in Full Range Solutions for New Construction and Refurbishment The ‘Beska’ Bridge – New Construction

The ongoing construction of ‘Beska’ bridge is taking part between Sika Solution the cities of and near the town of Beska as part HRWR / Superplasticizers of the full, 4-lane development of the E75 motorway (part of the Pan- n Sika® ViscoCrete®-3077/-5380 European Corridor 10). WR / Plasticizers n Plastiment® 20 R The Design-Build Contract includes planning and construction of this Other Admixtures & Additives bridge. With 2,213 m length it is the longest bridge construction in all of n SikaAer®, Separol® EP, Separol® N, Rugasol®-2 W, Serbia and the largest bridge in Europe currently being built. The bridge Sika Antisol® S, Betonloser is crossing the river with spans of 60 m + 105 m + 210 m Concrete Repair and Protection / Ready to use Mortars + 105 m + 60 m. Three bridge piers are constructed in the river. The n Sika® MonoTop®-610/-620/-910 N/-412 N, bridge have a height above ground of up to 40 m. The ‘cantilever meth- SikaTop®-122 SP, SikaTop® Armatec 110 EpoCem, od of construction’ was used to build the wide spans of the bridge SikaRefit® crossing the river. This girders were concreted and pre-stressed in Grouting short, balanced 5-m-sections on both sides of the piers at the same n SikaGrout ®-212/-318 time (balance beams). Once the centre of the span was reached, the Waterproofing / Injection framework carriage is moved to the next pier and the procedure was n Sikadur ®-Combiflex® SG-10 M 200, Sika® repeated until the overhanging girders joined in the middle of a span.

‘Gazela’ is the most important bridge in Belgrade across the Sava river. Sika Solution It was built within four years (1966-1970). Structural Bonding / Structural Strengthening n Sika® CarboDur® Lamelle S 812/S912/S1012 The bridge is 332 m long and 27.5 m wide, with three lanes in each n SikaWrap®-230 C Rolls 300 mm/600mm direction, and total road width of 21.8 m. It is constructed as a combi- n Sikadur®-330 nation of beam and arch, with shallow-frame beam and diagonal steel- n Sikadur®-30 concrete abutments. The maximum height of the span centre is 22.8 m Structural Bonding / Rigid Bonding at median water level. n Sikadur®-31/41 CF Normal Concrete Repair and Protection / Ready to use mortars The bridge is chief connection line between city center and New n SikaTop®-122 SP Belgrade, and also carries the transit traffic on E70 and E75 highways n Sikadur®-32 through Belgrade. As such, it is extremely overloaded and a cause of n SikaTop®-Armatec 110 EpoCem frequent congestion, as it leans on the main Belgrade’s Mostar inter- Concrete Repair and Protection / Concrete Protection change. On average over 160,000 vehicles cross it every day (not- n Sikagard ®-700 S withstanding the impeded flow), even it was designed to be used by n Sikagard ®-680 S Betoncolor 40,000.
