[0003] The pendulum friction coefficient tester is an important tool for measuring the friction testing platform. The bottom of the pendulum friction coefficient tester is a triangular support frame, and the three fixed frames are all detachable. During storage, each support will be disassembled for easy storage , and then install it after use, it is troublesome to repeatedly disassemble and install like this, it is very time-consuming and laborious, which makes the test efficiency low, and the existing test method is only to test the friction force of the road surface at one temperature, which is not conducive to the study of the temperature on the road surface friction force Impact

Description
technical field [0001] The invention relates to the technical field of expressway detection, in particular to a method for quickly measuring road surface friction. Background technique [0002] One of the biggest characteristics of expressways is the fast driving speed. Due to the continuous improvement of automobile performance, the actual driving speed on the expressway is often higher than the design speed. The important technical index reflecting the skid resistance of the pavement is the friction coefficient value of the pavement. [0003] The pendulum friction coefficient tester is an important tool for measuring the friction testing platform. The bottom of the pendulum friction coefficient tester is a triangular support frame, and the three fixed frames are all detachable. During storage, each support will be disassembled for easy storage , and then install it after use, it is troublesome to repeatedly disassemble and install like this, it is very time-consuming and ...
