Rapid Rehabilitation Techniques with Cement Concrete_ Applied on Deformed Asphaltic Roads

On asphaltic roads the so called «wash-boardeffect » in front of traffic lights is a well known phenomenon. Regular reconstruction of these areas places a significant and recurrent burden on road managing authorities. Because of the large volumen of traffic at these intersections repair works also lead to a huge traffic disruption. A permanent solution is the replacing of the affected area with a cement concrete surface. By using doweled prefabricated slabs or a vacuum treatment of concrete mortar it is now possible to install this concrete surface between two rush hour peaks. This paper describes the construction of two testsections with these new techiniques,
