Stabilization of slopes with a gradient of up to 60 degrees

Construction of the TV4 Project is to relieve a major twin rail bottleneck in the Trent Valley at Tamworth in Staffordshire by upgrading the capacity from two tracks to four to cut congestion and allow shorter transit times.

To increase the capacity and reduce traveling times, additional material was excavated from the embankment and an extra line on either side of the original two tracks was laid. Since some settlements are partly built very close to the railroad line, the resulting 60 degree embankment slopes were secured by a total of 5,000 self-drilling galvanized hollow bars of type MAI R38N in lengths varying from 4 to 11 m.
