Usage behavior and rheology

Dr.-Ing. Konrad Mollenhauer

Module Structural traffic route engineering

2 SWS, 3 credits, summer semester 

Desired learning outcomes 

To work out the systematic relationships between the mechanical properties of the construction materials used in traffic route construction and the service behavior of traffic route pavements, taking into account the influences of construction material production, installation and compaction. 

Content 

• Service behavior of building materials in traffic route construction:
  • Stiffness,
  • Crack resistance/strength,
  • Deformation behavior,
  • fatigue resistance,
  • Adhesion behavior,
  • durability,
  • Surface properties
• Rheology of road materials
  • Introduction to rheology,
  • viscoelasticity,
  • complex modulus of elasticity and shear modulus
  • simple modeling for the analysis of deformation properties of road materials

Examination achievements

• Seminar lecture on relevant construction material properties and their description by material models (40%)
• Written or oral exam (60%)
