Technical data:
- Extension of existing cross beams (without concrete):
- 100 steel pieces
- 14 wood pieces
- 8 aluminum pieces
- 200 pieces Relocation of cross beams
- 3,500 m removal of loose material at the foot of the embankment with local
landfill or on the road surface for breaking up - 750 m Repair existing pointed trench (0.1m3/m)
- 60 tons of natural stone blocks to be laid
- 50 m³ of unbound mixtures for selective improvement of the foundation layers to be delivered and installed
- 9,000 m² of road structure to be broken up/milled, leveled, and compacted
- 9,000 m² breaking/milling, leveling, compacting road structure
Object description:
The existing cross cuts (approx. 122 pieces) will be removed. Reusable cross cuts will be stored temporarily to the side for reuse. Loose material at the foot of the embankment will be removed and brought to the road structure for breaking up or, on the instructions of the site management, deposited in local landfills along the road. The existing V-shaped ditch (approx. 750 m) will be repaired. The material produced will either be brought to the road structure for breaking up or deposited along the road in accordance with the instructions of the site management. Culverts will be installed to drain the V-shaped ditch. In a further step, the existing forest road will be torn up to a depth of 25 to 30 cm and then processed to a depth of 30 cm using a crusher or milling machine. A graded grain size of 0/45 should be aimed for. The material will be used as a base layer and will be leveled and compacted for this purpose. At the same time, the profile of the road will be created. Around 200 cross cuts will be installed at intervals of approx. 20 m along the entire length of the road. A block formation approx. 1 m high, approx. 0.8–1 m deep and approx. 35 m long is created. In the area of the block formation, an approx. 70 m long drainage pipe is installed on the uphill side.
Requirements:
- Material management
- Mountain construction site
- Short construction time & logistics
Special features
Material balance: Material management takes place within the line construction site. The excavated material is placed on the road structure for crushing and milling.
