Fractal features of cracking of self-monitoring asphalt concrete

Self-monitoring asphalt concrete has a good electrical behavior. The monitoring of damage is valuable for structural health monitoring and service life prediction. In this paper, the process of cracking of self-monitoring asphalt concrete cracks were quantitatively described by indirect tensile test and combination of mathematical fractal theory. The test results show that the distribution of self-monitoring asphalt concrete crack has obviously statistical similarity, and cracks with a clear statistical significance of cracks on the fractal. There is a good congruent relationship among fractal dimension, resistance and deformation, which provides a new thought to the research of the cracking of self-monitoring asphalt concrete.
