Effect Evaluation Method of Foamed Asphalt Based on Digital Image Processing Technology
In view of the shortage of determining the optimal foaming parameters of foamed asphalt only by experience,this paper adopted digital image processing technology to collect images of the mixture of foamed asphalt and milled material RAI obtained under different foaming conditions and carried out grayscale image conversion,morphological processing,binary image conversion,and image segmentation,so as to calculate the asphalt wrapping rate in different areas.With the uniform dispersion of asphalt in the mixture as the indicator,the foaming effect of foamed asphalt was evaluated,and the optimal foaming parameters were determined.The results show that the digital image processing technology can quickly and effectively evaluate the uniform dispersion effect of the foamed asphalt,and the accurate value can be calculated as the basis for judging the optimal foaming parameters.The technology has the advantages of simple and quick operation,and it is easy to implement.
