Abstract

The invention discloses an asphalt mixture wheel tracking test device. The asphalt mixture wheel tracking test device comprises a main body with a sealed structure and a temperature control structure for providing temperature control in the main body, wherein the main body is internally provided with a main shaft and a motor for enabling the main shaft to rotate; the main shaft is uniformly connected with a plurality of hydraulic connecting rods; the end parts of the hydraulic connecting rods are connected with rubber rolling wheels; a fixing device for fixing a test piece is arranged just below the main shaft; the main body is further internally provided with a frequency conversion and speed regulating box for controlling the movement frequency of the motor. According to the device disclosed by the invention, the design of a counterweight block is omitted so that a series of problems caused by the counterweight block are solved; the temperature adjustment can be carried out so that tests under different temperature are realized.

Description

technical field [0001] The invention belongs to the technical field of asphalt pavement tests and relates to an asphalt mixture rutting test device. Background technique [0002] Asphalt mixture is a commonly used pavement material for high-grade highways or other driving roads at home and abroad, and because asphalt mixture is a viscoelastic-plastic material, it will produce obvious grooves, that is, ruts, under high temperature or heavy traffic volume. Severe ruts can affect driving safety and comfort. Therefore, it is very necessary to measure and evaluate the anti-rutting performance of asphalt mixture. [0003] At present, the asphalt mixture rutting test equipment used at home and abroad usually uses a reciprocating asphalt mixture rutting test machine, which mainly obtains ruts through reciprocating wheel pressure and rolling motion, and finally measures the performance of asphalt mixture according to the depth of the ruts. In order to simulate the rutting environme...
