Abstract

The invention discloses a multifunctional rut testing machine used for simulating road surface actual state. The machine is characterized by that: the machine comprises a testing platform, a driving mechanism used for driving the testing platform, a test piece fixture board used for fixing a test piece, a rut elevation height measuring device, a rut concavity depth measuring device, and a water circulation system. The testing platform is arranged on vertical supporting rods. The testing platform is positioned above the test piece fixture board. 2 elevation arms are arranged on the testing platform. A loading board is arranged on the upper part of the elevation arms. A testing wheel set is arranged on the lower part of the elevation arms. A supporting seat is arranged on the test piece fixture board, wherein the rut elevation height measuring device is arranged on the supporting seat. The water circulation system comprises a circulation water cistern and a water tank. A first water pump and a heating device are arranged in the circulation water cistern. A second water pump is arranged in the water tank. The test piece fixture board is arranged on the bottom of the water tank. With the multifunctional rut testing machine used for simulating road surface actual state, a plurality of functions can be realized, tests for a plurality of items can be carried out, and the actual road surface state can be simulated.

Description

technical field [0001] The invention relates to a multifunctional rutting testing machine for simulating the actual state of the road surface. Background technique [0002] Asphalt pavement is the mainstream structural form of highway pavement in our country. However, with the surge of traffic volume and the increase of heavy vehicles, the phenomenon of overloading is becoming more and more serious. The rutting damage of our country's highways is becoming more and more serious, causing huge economic losses. How to prevent asphalt pavement rutting has also become a worldwide problem. my country's codes require that the anti-rutting performance of asphalt mixture be tested in the design of asphalt mixture materials. In the current standard rutting test, the size of the rutting specimen (30cm×30cm×5cm), the ambient temperature (60°C), load (0.7MPa) and wheel speed (42 times / min) are fixed. The standard rutting test machine cannot simulate the characteristics of vehicle overload...
