REVISION OF SOUTH AFRICAN PAVEMENT DESIGN METHOD
REVISION OF SOUTH AFRICAN PAVEMENT DESIGN METHODPB/2006/D-1: IMPROVED DAMAGE MODELS FOR BITUMINOUS MATERIALS (PART 2 THIN SURFACINGS)Johan GerberUniversity of StellenboschAugust 2011SEAL MODELLING AND DESIGN1Approach to modellingModelling scales discussion
2Past work (Dr Terence Milne)
Finite element modelling3D Viscoelastic macro-scale pavement
Better mesh better output
42D Modelling has been done2D CT-Scan meso-scale model
5Acquiring basic modelling skillsIdeal seal structure exercise (2 layers of stone)
6Acquiring basic modelling skillsIdeal seal structure exercise (2 layers of stone)
7Current progressGranular base geometry establishmentExtracting in-situ samples
8Current progressGranular base geometry establishmentExtracted sample & representative CT-Scan
Reseal on G5 base
