Abstract
The present invention relates to a process for widening roadways. The process starts with digging a trench of adequate depth in the slope of the embankment of the existing roadway at a distance corresponding to the widening. A wall is then built in the trench by means of prefabricated elements or by on-site casting, and is subsequently anchored to the road embankment by means of tension elements. The wall rises substantially to the level of the roadway so as to define a channel which is then filled with stabilized material, on which the road paving is completed up to the wall.
