Composition detection device for high-modulus asphalt pavement

Abstract

The invention discloses a high-modulus asphalt pavement composition detection device, which comprises a detector, a device main body for needle penetration detection, a display and control system, a push detection assembly, a temperature control module, a standard needle and an extraction and cleaning auxiliary structure, is a three-way structure with a specified angle, and is fixed on the surface of the detector through a bolt; the two pins are initially symmetrically distributed on the two sides of the standard needle; through the arrangement of the detector and the extraction and cleaning auxiliary structure, the sample vessel can be automatically and accurately positioned and stably pressed, so that a sample is powerfully ensured to be positioned at an accurate position, the reliability of a detection result is greatly improved, and after standard needle detection is completed, the detection accuracy is greatly improved. According to the automatic cleaning device, comprehensive and thorough cleaning can be achieved, the workload of workers is reduced, meanwhile, automatic control is achieved in the cleaning process, manual intervention and errors possibly caused by manual intervention are greatly reduced, and it is ensured that the whole device can operate efficiently and accurately.
