THE CRACK GROWTH MECHANISM IN ASPHALTIC MIXES

The crack growth mechanism in asphalt concrete (AC) mixes is studied. In cyclic tests on several asphaltic mixes crack growth is measured, both with crack foils and with COD-gauges. It is found that crack growth in asphaltic mixes is described by three processes which are parallel in time: cohesive crack growth in the mortar, adhesive crack growth between the mortar and the aggregates and a crack stoppers process. Differences in overall crack growth in asphalt concrete are due to differences in the contributions of each individual process to the overall process.
