Problems solved by technology
[0005] The currently used rutting tester can only test one piece of asphalt mixture specimen at a time. Under normal circumstances, it can only test up to 7 specimens per day, which is very inefficient.
More importantly, different asphalt mixture specimens cannot be guaranteed to be tested under the same test conditions, which will affect the comparability of test results between different specimens

Embodiment 1
[0016] exist figure 1 Among them, the continuous multifunctional rutting tester of this embodiment consists of a constant temperature box 1, a displacement sensor 2, a wheel frame 3, a test wheel jack 4, a test wheel motor 5, a programmable controller 6, a test wheel 7, and a test piece fixing clip 8. Bracket 9, electric heater 10, pulley 11, rutting test plate 12, right sprocket 13, motor 14, right support seat 15, chain 16, upper chain plate 17, lower chain plate 18, roller bar 19, left support Seat 20, support jack 21, temperature controller 22, left sprocket wheel 23, display terminal 24 are connected to form.
[0017] Bottom in thermostat 1 is fixedly installed with left support base 20, right support base 15, motor 14 with threaded fastening connector, on the left support base 20, is connected with support jack 21 with connecting shaft, the upper end of support jack 21 and A support 9 is connected and installed on the right support base 15 . A temperature controller 2...
Embodiment 2
[0019] In this embodiment, three track test plates 12 are fixedly connected to the upper chain plate 17 with the test piece fixing clip 8 . Other components and the coupling relationship of the components are the same as in Embodiment 1.
Embodiment 3
[0021] In this embodiment, 16 track test plates 12 are fixedly connected to the upper chain plate 17 with the test piece fixing clip 8 . On the upper surface of the rut test plate 12, three test wheels 7 are respectively installed on the wheel frame 3 with the wheel axles. The wheel shaft of 7 is fixedly connected with a test wheel motor 5 with a threaded fastening connector, and the test wheel motor 5 drives the test wheel 7 to rotate on the upper surface of the rutting test plate 12 . Other components and the coupling relationship of the components are the same as in Embodiment 1.
[0022] Working process of the present invention is as follows:
[0023] When carrying out the rutting test, start the motor 14, drive the right sprocket 13 to rotate through the belt transmission mechanism, and then drive the left sprocket 23 to rotate through the chain 16, and the rutting plate test plate 12 installed on the chain 16 rotates together with the chain 16. The two test wheel jacks...

Description
technical field [0001] The invention belongs to the technical field of auxiliary equipment for building, repairing, repairing or removing roads or similar pavements, and in particular relates to a continuous multifunctional rutting tester. Background technique [0002] At present, the pavement of high-grade highways in my country is mostly made of asphalt mixture. Many road surfaces have oil flooding, potholes, ruts, cracks and other diseases soon after they are opened to traffic. Among them, rutting has become one of the main diseases of my country's expressways. There are many reasons for rutting on asphalt pavement. During the high temperature season in summer, under the load of overloaded vehicles, longitudinal grooves are formed on the roadway, sometimes accompanied by uplifts on both sides of the roadway. The research on the high-temperature performance of asphalt mixture has become an important topic for road researchers, and my country's "Test Regulations for Asphalt...
