Background

High-pressure water jet cutting is a non-traditional cold cutting method and has the advantages that the traditional cutting method is not comparable to. The method utilizes the impact action of high-pressure high-speed water flow on a workpiece to remove materials, and is sometimes called water cutting for short or water cutting commonly. The water cutting is divided into a high pressure type and a low pressure type, and generally 100MPa is taken as a limit. The high pressure type is 100MPa or more, and the low pressure type is 100MPa or less. And over 200MPa is ultrahigh pressure type. A pressure of 1Mpa corresponds to a force of 10 kg acting on a 1 cm square object. The high-pressure water jet has the advantages of low cost, simple structure, good cutting quality, no limitation by materials and thickness and no pollution.

Cracks are common diseases of asphalt concrete pavements, and the crack problem becomes more serious along with the increase of the using time. One is fatigue-type cracks, because the road surface is exposed to the environment for a long time and is influenced by the external temperature and the acting force, so that the structure is changed to some extent. At present, in the process of laying and maintaining expressways and common roads, pit and crack repairing of asphalt pavements is one of the most common operation projects. When a road surface is damaged, a road surface cutting machine is used for cutting rectangular thin lines around a damaged area, then the damaged area is crushed, new road surface materials are paved after the damaged area is cleaned up, and the purpose of repairing the road surface is achieved. This type of road surface cutting machine uses a saw blade rotating at a high speed to cut the road surface, which makes it necessary to manually draw money to be cut before the machine works to perform the shape cutting. And manual marking operation is troublesome, consumes long time and has low working efficiency. And often have irregularities in shape resulting in an unsightly cut shape.
