Abstract

The invention relates to a device for accurately cutting a pre-cut seam of an asphalt mixture semi-circular bending tensile test piece. The device comprises a horizontal operation platform, and an electric motor, a saw blade and a test piece fixator which are arranged on the horizontal operation platform, wherein the electric motor is in transmission connection with the saw blade; an adjustable jig and an adjusting bolt used for fixing the asphalt mixture semi-circular bending tensile test piece are mounted on the test piece fixator; 8 adjustable foot screws, a circular level and 2 millimeter graduated scales are further mounted on the test piece fixator; the 8 adjustable foot screws are arranged at the bottom of the test piece fixator, the circular level is arranged at the upper part of the test piece fixator, and the 2 millimeter graduated scales are arranged at the side part of the test piece fixator; a T-shaped sliding rail is arranged on the horizontal operation platform, the bottom of the test piece fixator is placed in the T-shaped sliding rail, and the test piece fixator can slide on the T-shaped sliding rail. The device has the advantages that equipment is simple, the cutting size can be controlled accurately, the cutting process is easy to control, and the applicability is high.

Description

technical field [0001] The invention belongs to the technical field of road engineering materials, in particular to a device for pre-cutting semicircular curved tensile test pieces of asphalt mixture with simple equipment, precise cutting size control, and easy control of the cutting process. Background technique [0002] At present, the common asphalt mixture cutting machine on the market can usually be used for cutting various types of larger specimens, including small beam specimens required for low temperature bending tests of asphalt mixtures, small beam specimens used for fatigue tests of asphalt mixtures, etc. As well as drill core sampling of gyratory compaction test pieces, etc., they are all easy-to-operate cutting test pieces, their accuracy is easy to guarantee, and the size deviation of the cut test pieces is not large. [0003] The shape of the test piece is irregular and the cutting requires more precise cutting. The cutting problem of the test piece needs to ...
