“…Dong Zhonghong [8] et al studied the transverse distribution law of dynamic response of semi-rigid base asphalt pavement under moving load, and found that the transverse distribution of vehicle wheel tracks was related to the fatigue life correction factor of asphalt pavement. Wang Zhi [9] pointed out that the repeated effect of traffic loads was the main reason for the development of pavement diseases, and verified the consistency of the transverse distribution law of pavement distress and the transverse distribution law of vehicle wheel tracks.Wang Hongchang [10] et al studied transverse fatigue crack extension based on a finite element analysis model, pavement cracking occurs firstly at the concentration of wheel tracks on asphalt pavement was found.…”

In order to improve the uniformity of wheel track transverse distribution when vehicles drive on asphalt pavement, delay the development of the asphalt pavement disease, and effectively avoid the waste of asphalt pavement design and maintenance resources, the relationship between vehicle wheel track distribution and road surface disease distribution is analyzed by the accurate identification method of traffic axle load dividing lane based on surveillance video, and then the influence of lane markings on wheel track distribution and asphalt pavement diseases was studied. Results show that:(1) The proportion and distribution of different vehicle types are accurately identified by SVM classifier based on object detection algorithm; (2) There was a high consistency between the distribution of asphalt pavement load-type diseases and the lateral distribution of vehicle wheel tracks; (3) The vehicle trajectory and pavement disease distribution on the asphalt pavement distributed more evenly if lane markings were swung and shifted. Based on above results, the swing and shifting method of lane markings, is proposed to achieve the redistribution of asphalt pavement wheel tracks by "swing and shifting" of lane markings. By using this method, the effective utilization rate of asphalt pavement could be improved, and asphalt pavement diseases could be improved, thus the service life of asphalt pavement could be extended. It provides a new idea for future maintenance of the asphalt pavement.

“…Asphalt pavement has the advantages of simple construction and comfortable driving, and more than 90% of expressways in China are paved with asphalt. Due to complex environmental changes and the increasing proportion of heavy-duty channelized traffic, conventional asphalt pavement is liable to be damaged during its service period, which makes the service quality of the road decline rapidly [2,3]. This is one of the main difficulties in the construction of high-quality modern highway systems in the new era.…”

In order to improve the service quality of roads and resolve the problem of defects in the conventional asphalt pavement in service, this paper uses a 5.3% aluminate coupling agent to modify the surface of nano-ZnO and prepares a composite-modified asphalt with nano-ZnO and basalt fiber (BF) as modifiers. First, the basic performance of different types of asphalt was investigated by means of a rotary film oven experiment. Then, a dynamic shear rheology experiment was carried out to analyze the high-temperature anti-rutting performance of the composite-modified asphalt at different temperatures and frequencies. Then, using a bending creep stiffness test, the low-temperature properties of the composite-modified asphalt were investigated. Finally, the microstructure and modification mechanisms of the composite-modified asphalt were analyzed with scanning electron microscopy and infrared spectroscopy. The results indicate that the anti-aging performance of the nano-ZnO/BF composite-modified asphalt is significantly improved after adding fibers to the modified asphalt. The average mass loss ratio is only 0.192%. At 46 °C, the rutting coefficient of the composite-modified asphalt was increased by 62.3%. The frequency master curve is always at the highest position and continues to rise, indicating a significant improvement in the high-temperature anti-rutting performance of the composite-modified asphalt. At 24 °C, the creep stiffness modulus S value of the composite-modified asphalt increased by 24.9%; moreover, there is no obvious effect of improving low temperature, but the variation range of creep tangent slope m of the modified asphalt after aging is decreased, which further shows that the addition of a modifier can decrease the influence of aging on asphalt. Nanoparticles are uniformly dispersed in the asphalt and form a three-dimensional interconnected structure with BF, which effectively improves the overall performance of the asphalt. Nano-ZnO and fibers have weak chemical reactions in matrix asphalt, but they are physically dispersed and compatible.
