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.
