Device for testing anti-skid performance of road surface

Abstract

The invention discloses a road surface anti-skid performance testing device. The device comprises a driving force part, a data acquisition part, a testing part and a pedestal part. The driving force part comprises a rotation speed control device, a motor and a driving shaft, and provides driving force for a test instrument and controls the rotation speed of a testing disk. The data acquisition part comprises a torque sensor and a data display, and the torque sensor is connected with the data display by a data line. The testing part comprises one testing disk, three rubber sheets are arranged at the bottom of the testing disk, the rubber sheets are in contact with a testing surface, and the driving shaft drives the testing disk to perform test. The pedestal part comprises a bearing plate, a bracket and three support screws, and ensures the tight and parallel contact between the testing disk and the road surface. Anti-skid performance tests are carried out on road surfaces of different configurations by the road surface anti-skid performance testing device so as to analyze the anti-skid performance of the road surfaces of different configurations and provide reliable test basis.

Description

technical field [0001] The invention relates to the field of anti-skid performance testing of road engineering pavement, in particular to a test device for anti-skid performance of road pavement. Background technique [0002] The determination of the anti-skid performance of the pavement is initially carried out according to the concept of friction mechanics, which involves the analysis of the friction mechanics between the vehicle tire and the pavement material and other influencing factors. Developed countries (such as the United Kingdom, France and the United States, etc.) began research on road pavement anti-skid performance testing technology in the late 1920s, and then held several international conferences on road surface characteristics. The research content mainly involves issues such as friction coefficient measurement technology and friction mechanism, slippery accidents, and anti-skid standards. These studies provide a theoretical basis and practical experience, ...

Problems solved by technology

[0007] The main detection methods currently used in our country are pendulum friction meter and sand-laying method. The test results of these devices are affected by factors such as test conditions, environment and operation process and show poor stability. The test results cannot truly reflect the road surface. The actual anti-skid performance, which leads to different results when they test the road surface of the same road section, and its efficiency and reliability cannot meet the needs of road management

On the other hand, although dynamic continuous detection has become the mainstream in the world today, it is more difficult to manufacture

At the same time, during detection, due to the complete braking of the detection wheel, the detection cost is relatively high
