pavements that are smoother from the start require less maintenance, saving road owners $1,295 annually for every lane-mile resurfaced (McGhee & Gillespie, 2006). One reason asphalt is the pavement of choice for engineers is the level of smoothness it provides. In fact, nearly 80 percent of pavement

When a uniform distribution is used, the time when the rutting depth reaches 15 mm will increase by approximately three years (to 14 years), and the annual maintenance cost will decrease by approximately 24.2% (at 276 000 yuan per kilometer). Therefore, automatic driving will effectively reduce the cost of maintaining the asphalt pavement.
