The invention discloses a test device of tensile and shear resistance of an asphalt material, belonging to the field of test devices of the asphalt material. The test device comprises a vertical anchor rod pull instrument, a suspended plate, a guide rod, a clamp plate, a fixed rod, a fixed end plate, a fixture, a transverse pull instrument, and an active plate, wherein the suspended plate is fixedabove the fixed end plate through the fixed rod, the clamp plate is connected below the suspended plate through the guide rod and can slide up and down, the fixture is arranged between the clamp plate and the active plate, two ends of the fixture are connected on the clamp plate and the active plate respectively, and the vertical anchor rod pull instrument is arranged at the top of the suspendedplate and penetrates the suspended plate so as to be connected with the top of the fixture. The vertical anchor rod pull instrument and the transverse pull instrument cooperate with the fixture, so asto well test tensile and shear resistance of the asphalt material. The test device has a simple structure, has good test effect, is convenient in test by people, makes test operation on tensile and shear resistance of the asphalt material more possible, and fills a blank of the field at home and abroad.
Description
technical field [0001] The invention relates to the technical field of water conservancy construction, in particular to an asphalt material tensile and shear strength test device. Background technique [0002] Compared with traditional cement concrete pavement, asphalt pavement has better driving stability, comfort and safety. After construction, asphalt pavement can be put into use earlier, and it is easy to maintain after operation and use. Therefore, it has been widely promoted and used all over the world. With the widespread use of asphalt concrete pavement, asphalt pavement disasters also occur and the trend is intensified, which not only puts forward higher requirements for the road performance of asphalt mixture. At the same time, it also raises deeper expectations for the performance of asphalt. [0003] At present, various scientific research institutes and universities mainly start with the three major indicators of asphalt materials in the detection of asphalt, n...
