Embodiment Construction

[0041] The present invention will be further described in detail below with reference to the accompanying drawings, which is an explanation but not a limitation of the present invention.

[0042] Such as figure 1 with 2 As shown, an infrared heating test device includes a heating device, a heat insulation device and a clamping plate 4. The bottom surface of the heating device, that is, the heating surface, is coated with infrared emitting material 9, which can effectively convert the heat generated by the heating plate into energy transmitted in infrared mode. The heating device is connected to the program-controlled power supply, and the program-controlled power supply is connected to the host computer; Cover the side walls and top surface of the heating device, and provide an insulating layer between the heat insulation device and the heating device.

[0043] Such as image 3 As shown, the heating device is provided with 4 bolt holes, the lower end of the double-ended stud 1 pass...

Abstract

The invention discloses an infrared heating test device. An infrared coating is arranged at the bottom of a heater; a heat-insulating device is arranged on the heater; the heater is arranged on acrossbeam of a test bench; a power adjusting device is connected with the heater; a plurality of temperature sensors are arranged on the surface of an asphalt sample at different depths; the temperature sensors and the power adjusting device are connected with an upper computer; the upper computer adjusts and controls output power of the heater through the power adjusting device and is used for acquiring data of the temperature sensors. The infrared heating test device regeneratively heats the asphalt sample under different constant heating powers so as to obtain infrared wavelength of highest heating efficiency.

Description

Technical field [0001] The invention relates to the technical field of highway engineering, in particular to a method and device for testing infrared material emissivity. Background technique [0002] With the rapid development of highways in our country, the previously constructed asphalt roads have been affected by factors such as rapid traffic growth, large-scale vehicles, serious overloading, and construction quality. As a result, the asphalt pavement is far from reaching the service life limit and there are cracks, potholes, Rutting, subsidence and other diseases, so it is urgent to properly maintain the asphalt pavement maintenance technology. The traditional maintenance methods are digging, milling, and grouting diseased asphalt pavements. This method will not only pollute the environment in the implementation of the project, but also cause a lot of waste of high-quality asphalt. [0003] Faced with this situation, it is necessary to adopt more environmentally friendly and ...
