EFFECT OF MATERIAL QUALITY AND COMPACTION ON THE MECHANICAL BEHAVIOUR OF BASE COURSE MATERIALS AND PAVEMENT PERFORMANCE

Recycled materials such as crushed concrete and masonry coming from demolishing buildings are widely used in the Netherlands for bases and sub-bases for road and airfield pavements. In order to be able to use these materials effectively, they should be characterised in terms of their shear strength, their resilient modulus and resistance to permanent deformation. This paper describes the main results of a large research programme that was carried out to assess these mechanical characteristics in relation to gradation, degree of compaction and composition. Also results of finite element calculations are presented which show the effect of the mechanical properties of these base course materials on the fatigue behaviour of the asphalt top layer and the permanent deformation that develops in the unbound base course. For the covering abstract see ITRD E118503.
