Procedure steps

Explanation video on our YouTube channel: "Knowledge Series"

 

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 der
  • Safeguarding of subterranean service pipes

Sp reading of cement

  • Qualification test for specification of cementc / 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% D Pr using suitable equipment
