The purpose of the project is directed at reviewing available techniques and equipment in selecting and developing a video-logging system used in obtaining a crack index for use in Arizona Department of Transportation Pavement Management System. During the first phase, a literature search was accomplished to evaluate all the electromagnetic means to gather the surface defect inventory including cracking. It was concluded that the video technology provided the best means of gathering this information and field tests were conducted with individual types of video cameras. High resolution color cameras provided the best means of computer enhancement of the video images were explored. In Phase II, field tests were conducted on four one-mile test sections of asphalt pavement in various states of distress. The field video images and the standard ADOT crack reference pictures were computer enhanced and a methodology was developed to directly compute the area of cracking.
