This research work utilizes image processing techniques and sand patch tests to measure pavement macrotexture Image processing techniques including median filter, Sobel edge detector, and circle fitting are used. The newly developed method is able to compute the pavement macrotexture depth index based on image of sand patch test. This image processing-based method is developed in Visual C#.NET framework 4.7.2. The newly developed program has been tested with real-world image samples.
