Description

technical field [0001] The invention relates to road maintenance and repair equipment, in particular to a trailer-type asphalt road maintenance operation vehicle. Background technique [0002] Since the reform and opening up, it has been the period with the fastest development, the largest scale and the most vitality in the history of China's highway transportation. Since the Shenyang-Dalian Expressway was completed and opened to traffic in 1988, China's highway industry has entered the stage of construction of expressways, first-class highways, etc. A new era dominated by high-grade highways. In just over ten years, our country has gone through the development process of developed countries for more than half a century. There are already 10 provinces in my country whose expressway mileage has exceeded 3,000 kilometers. Due to the development of road construction, the development of transportation has been driven. The quantity and proportion have been greatly increased. ...
