Gutzwiller’s Cost-Effective and Ecological Process

In situ recycling of existing materials (pebbles, bricks, tiles, concrete slabs, bituminous coated elements, etc.)

Conventional processes not only exhaust quarries, but also pollute the environment with transport vehicles.

For roads made with material fill-ins, crushing (grading) is done in situ. Therefore, this process reduces costs and improves results because we obtain a homogeneous material with a sufficient amount of fine materials to bind the traffic lane surface. Thanks to vibrating plates, an exceptional final result is obtained.

The technique consists of the following phases.

Ripping of the road to a thickness of 5-10 cm with the decompactor.

Crushing of the road on a thickness of 5 to 10 cm with the stone crusher to get materials for the new traffic lane.

Profiling : forming the road profile (banking or grading of top layer section) with a hydraulically controlled grader blade.

Compaction done with a vibrating plate, equipped with 3 independent articulated pads, adapting automatically to the road section.

When the roads have a granulometry (stone size) not exceeding 0 – 60 mm, a drill is used to repair a road because it allows regenerating the traffic lane surface. Drilling is followed by profiling, if necessary, and compacting.
