Asphalt wearing layer adhesive force testing device

The invention provides an asphalt wearing layer adhesive force testing device, which relates to the technical field of testing devices and comprises a base. When the electric cylinder shrinks, the connecting rod and the tooth row move upwards, after the tooth row moves upwards by 5 cm, the tooth row is meshed with the gear sleeve, then the gear sleeve and the worm are driven by the tooth row to rotate, the worm wheel can be driven when the worm rotates, and then rotation of the rotating shaft is achieved. Finally, switching between the test block and the reference block is realized, the equipment cost can be reduced on the premise of improving the test precision, the practicability is high, the problem that the performance of asphalt needs to be tested before the asphalt is used is solved, subsequent rework caused by unqualified asphalt is avoided, and if continuous adhesion test is carried out in the test process, the test efficiency is improved. At the moment, asphalt is adhered to the contact tip for reali
