USE OF COLOR PHOTOGRAPHY FOR PAVEMENT EVALUATION STUDIES IN MAINE

TWENTY-TWO DIFFERENT AIRPHOTO COVERAGES OF A SHORT SECTION OF INTERSTATE WERE TAKEN OVER A ONE YEAR PERIOD USING THREE TYPES OF COLOR FILM AND TWO TYPES OF BLACK-AND-WHITE. SCALES OBTAINED VARIED FROM 100FT./INCH TO 1,000FT./INCH. A TECHNIQUE FOR COMPARING THE RELATIVE AMOUNT OF DETAIL DISCERNIBLE ON THE DIFFERENT PHOTO COVERAGES WAS DEVELOPED. IT WAS CONCLUDED THAT THE MAXIMUM AMOUNT OF INFORMATION ON PAVEMENT DISTRESS FEATURES CAN BE EXTRACTED FROM EKTACHROME INFRARED AERO TRANSPARENCIES. FOR RECONNAISSANCE SURVEYS OF PAVEMENTS, A SCALE OF 500 FT./INCH IS ADEQUATE; FOR DETAILED STUDIES, A SCALE OF 200 FT./INCH OR LARGER IS SUGGESTED. /AUTHOR/
