Description

Technical Field

[0001] The utility model relates to the technical field of road wear resistance detection, and more specifically to a wear resistance detection device for road construction. Background Art

[0002] Highways refer to public roads between cities, between urban and rural areas, and in the countryside that have been approved by the transportation authorities and can be used by cars. Cement concrete pavement is an important part of highway transportation. Its wear resistance is of great significance to ensuring the normal operation of highways and extending the service life of pavement. Therefore, after the pavement is constructed, the pavement's wear resistance needs to be tested. However, when testing the existing pavement's wear resistance, it is not convenient to simulate the temperature of the pavement, and it is not convenient to test the wear resistance of pavements at different temperatures, which affects the quality of the test; and tiny waste chips will be generated during the wear resistance test. If they are not cleaned, they will adhere to the pavement test sample and the friction wheel, affecting the accuracy of the wear resistance test. For this reason, we propose a wear resistance detection device for pavement construction. Utility Model Content
