An asphalt mixture ice melting effect and noise testing device and method

Abstract

The present invention relates to the technical field of asphalt mixture pavement, in particular to a device and method for testing the ice-melting effect and noise of asphalt mixture, comprising: a sound-proof temperature-controlled environment box, and a refrigeration device and a heat-preservation device are arranged in the sound-proof temperature-controlled environment box for use It is used to simulate the icing environment on the road surface; there is a test bench at the bottom of the sound-proof temperature-controlled environment box, and asphalt mixture specimens are fixed on the test bench; tire fixing parts are also set in the sound-proof temperature-controlled environment box, and standard tires are fixed on the tire fixing parts , the standard tire is fixed directly above the asphalt mixture specimen, when the tire fixing part is opened, the standard tire falls from a certain height onto the asphalt mixture specimen, and a camera and a noise tester are also installed in the sound-proof temperature-controlled environment box , the lens of the camera is aimed at the contact surface between the asphalt mixture specimen and the standard tire, and the noise tester is used to measure the sound when the standard tire touches the asphalt mixture specimen; the height of the tire fixing part from the asphalt mixture specimen can be adjusted Adjust settings.

Description

technical field [0001] The invention relates to the technical field of asphalt mixture pavement testing, in particular to an asphalt mixture ice-melting effect and noise testing device and method. Background technique [0002] Asphalt pavement has the advantages of good flatness, high driving comfort, convenient construction, convenient maintenance and repair, etc. It is the main pavement type of high-grade highways at present. In recent years, with the gradual improvement of economic living standards, people's requirements for road surfaces are getting higher and higher, and asphalt pavement is constantly changing from the use type to the function type. How to pave a new type of pavement that is green, sustainable, and has specific functions such as anti-rutting, long life, ice and snow melting, and noise reduction is a new trend in current asphalt pavement construction. [0003] For urban roads, pavement with functions of melting ice and reducing noise has become the focu...

AI Technical Summary

Problems solved by technology

Based on the research on existing asphalt pavement ice melting and noise reduction technology at home and abroad, it can be found that although there are various test methods for snow melting effect evaluation and noise testing, there is no standard test and evaluation method. There are certain limitations, or the price is expensive, the economy is poor, or professional equipment is required, and the practicability is insufficient
