Traditionally, fatigue cracking in asphalt pavement means fatigue failure, which is the basis for controlling the design thickness of asphalt pavements. In fact, the fatigue failure of asphalt pavements includes three stages: fatigue cracking, crack expansion, and structural failure. Therefore, this paper aims to investigate the fatigue life …

The ViT module was added to the neck of YOLO V5 to improve the speed and accuracy of the model. 1944 asphalt pavement images were collected for testing. The test results showed that the proposed model obtained high accuracy and speed for longitudinal, transverse, and fatigue cracks and was capable of real-time detection.

Alligator cracking resembles the pattern of alligator skin, and it typically occurs as a result of a combination of factors, including heavy traffic loads, poor drainage, and the aging of the asphalt surface. The repeated stress and strain on the pavement cause interconnected cracks that resemble the scales of an alligator.

Therefore, the data set used in this study are all the picture sets of highway asphalt pavement cracks. Because the cracks on the asphalt pavement do not differ much from the color of the pavement itself, they often coincide with the white line of traffic on the pavement, and there are gaps at the links of two high-speed road segments, and the

Coat the vertical surfaces of the crack with a small excess of filler deposited in the bottom of the crack. To prevent tracking, the filler should be 1⁄8 to 1⁄4 inch below the top of the crack. If necessary, use a squeegee to remove excess sealant on the pavement surface, and then blot with sand or limestone dust.

Combined with the structural layer information of the asphalt pavement test section (as shown in Figure 2), it can be seen that the transverse cracks in K2+421, K2+520, K2+572, and K2+650 are mainly caused by the complex stress of pavement structural layer materials [24,25]. Therefore, in the calculation and analysis, the problems …
