Crack geometry analysis in asphalt samples obtained from a Heavy Vehicle Simulator test site

This study compared vertical crack propagation in samples obtained from a HVS (heavy vehicle simulator) test site and to know whether cracks propagate through all the asphalt layers, and if not, how deeply they penetrate. The purpose was also to investigate any correlation between compaction grades and crack appearance as well as the effect of bonding between asphalt concrete layers. An enhanced technique of marking and recording hairline cracks in the surface is described.
