| Abstract: | The exposed-aggregate surface of EACCP possesses some advantages,such as big stiffness,high slide,low noise,anti-glare,etc.By using basic method of digital image technique,the image pixel values of the exposed-aggregate surface are quantitatively calculated.The relational model between the average of pixel difference and surface texture depth is established.According to large numbers of digital images on the EACCP,the surface texture depth of corresponding sites is calculated.Finally,exposed-surface structure quality of EACCP can be evaluated.Application Example shows that method of digital image technique can quickly test surface texture depth of EACCP,and can be easy to achieve measurement of continuous work. |
