AASHO Test Road Loop
This is the surviving test road loop near Ottawa, Il. There were six loops at the test site when constructed in 1956-58. The loops were approximately one mile in distance. One leg concrete the other asphalt. This photo is looking West from the East end of the loop. I-80 is to the far right. The other five test loops were situated where I-80 runs today. This particular loop was used for testing the effects of weather on the pavement.
(NOTE: I took this shot with my digital camera mounted to the top of a 12 foot pole. I set the timer and positioned the camera with about 4 seconds to go. I also shot some video using this technique but, my aim was off and not as good as the stills.)
