Abstract

Belonging to the technical field of asphalt performance testing, the invention in particular relates to an instrument and method for measuring the volume change of an asphalt mixture test piece during induction heating. The instrument comprises an electromagnetic emission device, telescopic conductive connecting rods, a temperature sensor A, a temperature sensor B, a temperature sensor C, a temperature sensor D, a temperature sensor E, camera positioning devices, cameras, scale, a test piece 11, patches, fixation rods, an interface, a screen, a control keyboard, an alternating-current generator, an image analysis device, a wind-heat temperature control device, a connecting rod control device, an image acquisition device control system, a control cabinet, a controller, an environmental cabinet and a telescopic rod. Compared with the prior art, the instrument provided by the invention has the advantages of simple structure, convenient operation, and good use effect, and can simply and rapidly measure the volume change condition of the asphalt mixture test piece during induction heating. Also, the induction heating process is easy to control.

Description

technical field [0001] The invention belongs to the technical field of asphalt performance testing, and in particular relates to an instrument and a method for measuring the volume change of an asphalt mixture specimen during induction heating. Background technique [0002] Asphalt concrete pavements can self-heal at room temperature, but at a very slow rate and require no cycling of traffic loads. When the binder in the asphalt mixture is exposed to high temperature during the intermittent period, the healing rate of the asphalt will increase, and asphalt healing will repair the cracks and looseness of the asphalt concrete pavement caused by low temperature, fatigue and base reflection, so it will improve the asphalt concrete pavement. service life, reduce pavement maintenance and repair, and bring economic and traffic benefits. Compared with repair measures such as sealants, asphalt concrete pavement self-healing technology will not bring negative effects on the repaired ...
