Abstract

The invention belongs to the field of pavement material detection, in particular to a pavement material strength test device with multiple detection functions, and the following scheme is proposed. A cross bar is fixedly connected between the fixed columns, a rotating rod is connected to the top of the fixed column, and rotating rollers are installed at both ends of the rotating rod. A transmission belt is connected between the two rotating rollers on the same side. The output shaft of the motor is connected, the transmission belt is fixedly connected with a mounting ring through a connecting rod, a mounting post is slidably connected in the mounting ring, the bottom end of the mounting post is fixed with a base, and a shock absorber is connected between the base and the mounting ring . The invention can cut the real pavement material and fix it in the installation groove, and then realize the real pavement material detection through the rotation of the tire.

Description

technical field [0001] The invention relates to the technical field of pavement material detection, in particular to a pavement material strength test device with multiple detection functions. Background technique [0002] With the comprehensive development of my country's transportation industry, road construction is particularly important, and the pavement materials and roadbed test and detection methods related to road construction are also receiving increasing attention. [0003] Pavement material strength testing instrument is an instrument and equipment for testing the strength index of high-grade highway subgrade and pavement materials. . [0004] Most of the existing pavement material strength test devices only have one or two functions, the detection effect is good, and they cannot simulate the real pavement environment. Therefore, we propose a pavement material strength test device with multiple detection functions. SUMMARY OF THE INVENTION [0005] The present...
