Technical Field

[0002] Road engineering refers to the entire process of planning, design, construction, maintenance and management of roads and the engineering entities involved. Like any other type of civil engineering, road engineering has obvious technical, economic and management characteristics.

[0003] Non-destructive road testing refers to a test method that can measure and inspect parameters such as thickness, steel bar position, internal defects, and certain physical and mechanical parameters without damaging the road surface. Non-destructive road testing refers to a test method that can measure and inspect parameters such as thickness, steel bar position, internal defects, and certain physical and mechanical parameters without damaging the road surface. It is generally carried out using acoustic and electrical principles and radioactive isotopes with the help of electronic instruments. For example, microwaves or sound waves are used to reach the required depth by selecting the frequency, and then the density, strength, and thickness of the road surface are measured based on the difference in dielectric constant or sound speed in different layers of materials. The advantages are: no destructive effect on the road surface; fast detection speed, and can be tested at any time and repeatedly.
