The degree of concrete surface roughness contributes to the bond strength between two concrete surfaces for either new construction or repair and retrofitting of concrete structures. Provided are novel systems and methods with industrial application to quantify concrete surface roughness from images which may be obtained from basic cameras or smartphones. A digital image processing system and method with a new index for concrete surface roughness based on the aggregate area-to-total surface area is provided. A machine learning method applying a combination of advanced techniques, including data augmentation and transfer learning, is utilized to categorize images based on the classification given during the learning process. Both methods compared favorably to a well-established method of 3D laser scanning.
