Abstract
The correct compaction level is crucial for the realisation of high quality asphalt roads. However, reaching the correct compaction level requires knowledge of the material behaviour during compaction; the material change from just slightly compacted into densely compacted. The paper discusses how a material model adopted from soil mechanics is tested for modelling the material behaviour of asphalt mixes. In the first part of the paper the Hveem Stabilometer is discussed, an existing test device that is modified to make it capable to measure material parameters during asphalt compaction. The second part of the paper discusses the results of a laboratory-measuring programme. Mixes with round material, different bitumen viscosity (equivalent to material temperatures) were tested under different applied stress combinations.
