WS 2500 is ploughing the terrain at full speed.

Soil stabilization on the A14 motorway in Germany

The A14 project aims at linking the former A241 in Mecklenburg-Vorpommern to the existing A 14 in Saxony-Anhalt. The northernmost section of the A14 motorway has closed the gap between the state capital of Schwerin and the Hanse town of Wismar.

One of the biggest challenges was the extremely poor nature of the existing soil on the 11.7 km long section of road between Jesendorf and the motorway junction at Wismar. Around 264,000 m² of subgrade level needed to be stabilized at working depths varying between 15 and 20 cm.

Its field-proven drive concept enabled the tractor-towed stabilizer WS 2500 from Wirtgen to achieve daily production rates of between 6,000 and 7,000 m². Mixing the existing soil with cement produced a clean and perfectly even surface across the stabilizer’s full working width of 2.50 m. Given the very harsh working conditions on the job site, Wirtgen’s quick-change toolholder system HT11 scored top marks as well by offering excellent resistance to wear and tear.

The contracting company had set the ambitious goal of completing the stabilizing operation on time, regardless of the poor soil condition along the A241. The site manager relied on the consistent performance of the tractor-towed stabilizer to meet this goal, “The WS 2500 not only delivered excellent results but was also twice as fast as its competitors. It impressed us with its mature engineering and high efficiency.”
