A method of using an infrared non-destructive flaw detection device for modified asphalt pavement

Abstract

The invention discloses a method for using an infrared nondestructive flaw detection device for modified asphalt pavement, a method for using an infrared nondestructive flaw detection integrated dual-purpose device for modified asphalt pavement, comprising the following steps: closing the screen door, according to the material properties Select electromagnetic excitation heating or microwave excitation heating; close the excitation device, stop heating, control the excitation plate to move to both sides, open the screen door; open the infrared camera to take pictures of the heating unit. For the conversion of excitation and microwave excitation, different excitation heating methods can be selected according to different modified asphalt pavements. When the modified asphalt pavement is added with soft magnetic particles, magnetite powder, activated carbon, carbon nanotubes, graphene and other modified materials Microwave excitation can be selected; electromagnetic excitation is used when adding modified materials such as metal and carbon to the modified asphalt pavement. The heating method is flexible, one method is dual-purpose, and the application range is wide.

Description

technical field [0001] The invention belongs to the technical field of infrared non-destructive flaw detection on pavement, and in particular relates to a method for using an infrared non-destructive flaw detection device for modified asphalt pavement. Background technique [0002] The development of transportation is an important guarantee for a country's national economy, and the foundation of transportation is roads. Without roads, material transportation and personnel travel cannot be carried out. To ensure the development of transportation, the quality of road engineering must be guaranteed. Therefore, on the premise of not damaging the pavement or raw materials, the method of inspecting the surface and interior of the pavement material under inspection, that is, non-destructive testing technology, is of great significance to road construction and maintenance. Although there are many non-destructive detection methods, such as ground penetrating radar, drop weight deflec...
