Investigations to check the air void content as a compaction requirement for fine-grained soils and cohesive mixed soils


  • Consistency and plasticity are decisive for soil mechanical properties of fine- and mixed-grained soils
  • Damage to earth structures by reducing consistency due to water ingress


  • Determination of the influence of the air void content on the deformation behaviour of compacted fine- and mixed-grained soils
  • Estimation of the advantages of tightening the requirements for the proportion of air voids with regard to the long-term load-bearing capacity and serviceability of earthworks


  • Classification tests - Proctor tests - Oedometer tests - Field tests
