This report discusses the relationships between the ability to observe pavement distress (cracking) as a function of sun position, travel direction, time of year and atmospheric conditions. The study is performed with images obtained via ConnDOT's Photolog vehicle, which were places on laser videodiscs and viewed with the ConnDOT Photolog Laser Videodisc System. Data were collected on two routes containing flexible pavements by filming each route hourly on five days between July 16 and September 14, 1992, from 9:00 a.m to 3:30 p.m. General observed relationships indicate that the ability to detect and quantify cracking varies by travel direction between north and south, and by time of day for east and west directions. Atmospheric visibility also affects the resultant distress rating such that with lowered visibility due to haze or fog, the variation by time of day is less than on clear days, particularly for transverse cracking.
