Concrete is removed and replaced with asphalt over a total distance of 14 kilometers. In the area between Oud-Turnhout and the Dessel-Schoten canal, a more in-depth basement analysis had to be carried out before any structural renovation could be carried out. In order to be able to demolish the existing continuous reinforced concrete, an ultrasonic grinding process was used. Thanks to this unique process, the existing concrete is completely crushed and separated from the reinforcement, which ultimately means a minimum of vibratory pollution for the environment and an enormous saving of time. After demolition, the existing foundation is stabilized with cement and looks like new. Then, 12.4 km of New Jersey concrete poured in place is laid over it. Recycled concrete from demolition is then used to manufacture 90,000 tonnes of new cement-bonded foundation in the on-site concrete plant. The new asphalt pavement is laid in three layers for a total of almost 80,000 tonnes of asphalt, the top layer of asphalt being laid without longitudinal or transverse joints.
