| 摘要： | Driverless trucks, their triple trailers in tow, drone through the sweltering days and frigid nights of western Nevada's high desert. They will travel steadily along their 2.9-km oval track at a constant 65 kph for up to 21 hours a day, 7 days a week, for 2 full years. WesTrack is a state-of-the-art pavement performance project being carried out at the Nevada Automotive Test Center. The specially built track contains 26 test sections that will provide valuable information on hot-mix asphalt (HMA) construction. The specific purpose of WesTrack's multiple test sections is to duplicate the range of materials and construction quality that may be found on the nation's roadways and demonstrate how well or poorly they perform relative to each other. Performance is being monitored by watching the development of rutting and fatigue cracking in each section. |
