Milling of the old asphalt
• Milling of the old asphalt layers
• Up to 10 cm of the old asphalt material can be mixed together with the cement-EvoCrete®-mixture | Special Grubber in action
• Cracking of the old layer material
• Big stones were brought to the surface
| Stone crusher in action
• Milling of the mixed layer material with the stone crusher to a grain size < 50 mm
|
Preparation of surfaces
- Secure trafficability for construction equipment
- Reduce water content of soil, if required
- Exchange soil, if required
- Pre-leveling / pre-compaction of rough grade level
- Obstruction-free trafficability of the area
- Marking / pegging of stabilization area
- Safeguarding of subterranean service pipes
| Spreading of cement
- Qualification test for specification of cementic / additive mixture
- Production of EvoCrete®-cement-mixture
- Preparation and use of suitable spreading vehicle
- Supervision of spreading procedure
| Mixing of cement
- Mixing of cement / additive mixture in required strength using soil stabilizer
- In the case of milling depths required > 50 cm, the soil must excavate, stored on site and mixed with EvoCrete® and cement and reused
|
Irrigation of surface
- Irrigating the base layer (evaporation protection) using an irrigation unit
- Continual adding of water without interrupting the milling work
- Filling procedure using vacuum tanker
| Levelling of the surface
- On-site creation of precise grade level
- Post-profiling with grader (laser controlled)
| Compaction of the surface
- Dynamic and / or static compaction on average 100% DPr using suitable equipment
- Compression of precise grade level using rubber tyred road roller on average 100% DPr using suitable equipment
|
Quality assurance
- Geotechnical support using static plate tests according to DIN 18134 and using dynamic plate tests as well as falling weight equipment
- Removal of drilling cores
- Compression strength tests, etc.
