Abstract
This study aims to examine hot asphalt mixtures in terms of 1) differences in fatigue failure characteristics with different mixing proportions of components, and 2) the distribution of the numbers of stress applications to reach of fatigue failure for hot asphalt mixtures.
Field surveys on fatigue cracking of roads in service and laboratory tests on stress fatigue confirmed that hot asphalt mixtures with different mix proportions differ to a statistically significant degree in the number of stress applications to reach fatigue failure. The life of the asphalt concrete layer is depends greatly on the mixing proportions of components of the bottom layer.
