Abstract

The invention relates to a production device and method of a sample for measurement of induction heating volume change of an asphalt mixture. The production device comprises a control box; a Marshall test piece bearing platform is arranged on the plane of the control box; the control box includes a box body, an electronic circuit board and a hydraulic pump in the box body, and a control button on the outer side wall of the box body; a controller is mounted on the electronic circuit board; the control button and the hydraulic pump are both connected with the controller; two displacement controllers are elliptic, and are symmetrically arranged on two sides of the Marshall test piece bearing platform; position fixed rods are 7-shaped, the lower ends thereof penetrate through the displacement controllers to connect with the hydraulic pump, and the upper ends thereof penetrate through rotating joints of movable rods to connect with the movable rods; and the movable rods are provided with patch clamping grooves. Compared with the prior art, the production device is simple in structure and convenient for operation, can simply, quickly and precisely fix two patches on two sides symmetric bout the diameter of a Marshall test piece, and is easy for controlling the sample production process.

Description

technical field [0001] The invention belongs to the technical field of asphalt performance testing, and in particular relates to a preparation device and method for a sample used for measuring the volume change of asphalt mixture by 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 re...
