Problems solved by technology
[0004] The repair device in this process is too clumsy to achieve flexible road repair, it is inconvenient to move, and the need for external circuits is too troublesome, and it cannot exert the proper repair effect on hard roads. There is no driving device, and the entire work needs to be completed manually. Not conducive to saving manpower

The invention belongs to the technical field of pavement repairing, in particular to an expressway asphalt pavement repairing process, comprising a frame, a bearing plate, a battery cabin, an air storage chamber, a driven wheel, an air nozzle, a crushing mechanism, a heating device and a roller; A seal air bag is arranged between each of that brackets and the machine frame, each air bag is provided with a plurality of springs fixedly connected with a corresponding bracket and a frame, each of the airbags is in communication with a second solenoid valve through a trachea, the vibration generated during the operation of the device drives the air bag to inflate the air storage chamber, so that resource can be reused, the driving end of each of the pneumatic cylinders is provided with a crushing rod, The left side of the pneumatic cylinder is provided with a third solenoid valve fixedly connected to the machine base, and the third solenoid valve is provided with an air pipe communicated with the air storage chamber. The air pressure in the pneumatic cylinder is controlled by the third solenoid valve, so that the crushing rod is instantaneously lowered and raised, and the uncrushed roadsurface between the two crushing wheels is further crushed.
Description
technical field [0001] The invention belongs to the technical field of pavement restoration, in particular to an expressway asphalt pavement restoration process. Background technique [0002] In high-grade highways, asphalt pavement is valued by countries all over the world for its well-known good performance. , no dust, small vibration, low noise, short construction period and easy maintenance and repair, etc., are widely used in expressways. With the development of highways in my country and the increase of traffic volume, rutting is the main form of damage to asphalt pavement. Rutting is the accumulation of permanent deformation in the vertical direction of the wheel track belt on the roadway under repeated wheel loads. When it is serious, there are usually bulging deformations on both sides. It is mainly caused by viscous flow of asphalt mixture, deformation of soil foundation and base course, and includes a certain degree of compaction and material wear. [0003] Som...
