Asphalt mixture rutting test device

Abstract

The invention discloses an asphalt mixture rutting test device, comprising: a box body; a support platform arranged in the box body, a fixed shaft is arranged on the support platform, and a rotating plate is rotatably connected to the fixed shaft. The rotating plate includes a test template, a connecting plate and a transmission plate connected in sequence from left to right; the motor is arranged in the box and is located below the transmission plate, and the motor drives the transmission plate to swing back and forth The pressure rod is hinged on a short side wall of the box body, a connecting rod is arranged downward in the middle of the pressure rod, the end of the connecting rod is connected with a roller, and the end of the pressure rod is provided with a counterweight so that the rollers are pressed against the surface of the asphalt mixture test form on the test form. The invention can simulate the actual driving condition on the asphalt mixture test mold of the turning or U-turn road section through the reciprocating swing of the asphalt mixture test mold, and can more accurately provide the rutting test data of the asphalt mixture of the turning or U-turn road section.

Description

technical field [0001] The invention relates to the field of asphalt pavement testing equipment. More specifically, the present invention relates to an asphalt mixture rutting test device. Background technique [0002] With the rapid development of expressways in my country, more and more attention has been paid to the performance of asphalt pavement. Rutting not only reduces the service life of the pavement, but also seriously affects the driving safety. Rutting has become the main disease of asphalt pavement. The permanent deformation of asphalt mixture at high temperature, the rutting test is a simple and easy method to evaluate the high temperature deformation of asphalt mixture. However, most of the current rutting test devices are linear reciprocating rutting tests. However, on some turning or U-turn road sections, the actual road conditions are often different from those of straight-line driving sections. Or the actual stress state of the asphalt mixture in the U-tur...

Problems solved by technology

However, most of the current rutting test devices are linear reciprocating rutting tests. However, on some turning or U-turn road sections, the actual road conditions are often different from those of straight-line driving sections. Or the actual stress state of the asphalt mixture in the U-turn section, so there is an urgent need for a rutting test device that can test the asphalt mixture laid on the turning or U-turn section.
