Rehabilitation of the federal motorway, Germany
The concrete revetment on a length of 4.5 km between Hanover and Kassel was rehabilitated.
The section from the Hildesheimer Börde area to the village of Derneburg of the federal motorway A 7 between Hanover and Kassel - an important connection for the North-South traffic - was built in 1958/62. On the occasion of the repair works of the concrete revetment on a length of 4.5 km of the section in question, each concrete slab was rehabilitated by injection, then asphalted.
