Abstract

It is a road surface binding strength test device, which is located with a motor on left side and a decelerator connected with motor through the transmission structure on right side. The decelerator is located with photoelectricity coder and programmable controller, which are connected with computer through cable and photoelectricity coder. There locate moment balance bar and control structure with its top connected with decelerator and its bottom connected with eccentric mechanism on the rack. The bottom of the eccentric mechanism is located with a pull sensor or torque sensor connected with clutch. There locate a clamping structure on the pull sensor or bottom of torque sensor.

Description

technical field [0001] The invention belongs to the technical field of force measuring equipment, and in particular relates to a tester for the bond strength between pavement layers. Background technique [0002] The structure of the asphalt pavement is generally to pave the asphalt mixture surface layer on the semi-rigid base layer stabilized by cement or fly ash. The asphalt mixture is generally used as the pavement layer on the bridge surface. The bonding between the asphalt surface layers, between the surface layers, and between the asphalt pavement layer and the cement bridge deck is very important. [0003] The instrument specially used to test the tensile force of asphalt pavement or bridge deck is the bridge deck waterproof layer puller, which is powered by a motor and adopts the structure and principle of a screw lifter. During the test, the lower end of the asphalt mixture specimen is fixed on the fixture, and the screw lifter structure pulls The upper end of the ...
