New construction of roads and expansion of existing roads

Public road planning must be carried out carefully in order to avoid later damage.

How is the formation laid?

(see submissions of asphalt work www.asphalt.de)

New construction of roads:

  • Assessment of the construction class in accordance with regional/national building regulations
  • Determination of the overall thickness of the frost-proof superstructure in accordance with regional/national building indications
  • Selection of the method in accordance with the technical, economic viewpoint and, where applicable, local features
  • Determination of the overall thickness of the frost-proof superstructure in accordance with regional/national building indications
  • Selection of the method in accordance with technical, economic viewpoint and, where applicable, local features

The expansion of existing roads:

  • Appraisal of the existing building structure
  • Selection of the renewal class in accordance with regional/national building regulation
  • Replacement of unsuitable components in the existing structure with suitable building materials and building material mix
  • Testing of the improvement of the drainage features, where necessary
  • Integration of mineral filled asphalt as reinforcement with suitable layer formation

Stresses

Testing for particular stresses is absolutely imperative

Particular stresses can be, for example:

  • Driving in one traffic lane only and tight cornering
  • Slow moving traffic
  • Frequent braking and acceleration
  • Bus bays and stops
  • Stop-and-go-traffic
  • Particularly high temperatures over an extended period of time
  • Intensive solar radiation

Please ensure that all structures are always in accordance with regional/national building (additional technical terms and guidelines for base course in road building)
