Description

Technical Field

[0001] The utility model relates to a device for photographing aggregate adhesion evaluation test results. Background Art

[0002] The adhesion between asphalt and aggregate is one of the important parameters to ensure the water stability of asphalt mixture. The traditional boiling method for asphalt-aggregate adhesion has been shown in practice to be unable to accurately evaluate the adhesion performance. For example, the adhesion between SBS modified asphalt and aggregate is level 5, and it is impossible to judge the difference in adhesion between aggregates of the same lithology and different sources. The European standard prEN 12697-11 proposes the use of the rotating bottle test as an aggregate adhesion evaluation method. Many studies have shown that the use of the rotating bottle and image processing method can better evaluate the aggregate adhesion performance.

[0003] Taking photos of the results of the rotating bottle test is one of the key steps in image processing evaluation. However, in actual operation, the asphalt on the aggregate surface will form reflection points, shadows and other problems due to factors such as lighting and sunlight. Reflection points will cause large calculation errors in the image processing results. Even if software such as Photoshop is used to process the image, it is still difficult to process the image accurately. Utility Model Content
