Process for forming gutters (gullies) provided at the edges of roadways and produced using bituminous coated materials and device for its implementation

摘要

This process consists in tipping the material into the trench, spreading it out regularly therein and then forming, using a vibrating plate the same shape as the gutter (gully) to be formed, the shape of the gutter and the compaction of the material at the same time. Preferably material should be used having a high module of richness, i.e. having a bitumen content higher than that of traditional coated materials. <IMAGE>
