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. ...

AI Technical Summary

Problems solved by technology

The mixing equipment used is generally inclined and fixed blade stirring type of the cylinder, which has a simple structure, but the ratio of oil to stone is difficult to control, and manual mixing is labor-intensive

However, most of the large comprehensive asphalt road maintenance vehicles are arranged on the chassis of medium and light vehicles, and it is still difficult to be commonly used in road maintenance teams at present.
