A reflective sign sheeting study was initiated in the Fall of 1973 for the purpose of comparing the relative performance of five reflective sheetings, i.e., 3M Engineer grade, 3M Commercial grade, Sunlite, Adcolite, and Maclite. A total of 361 test signs containing these five sheeting were placed in Districs 2 and 3 for field exposure. These signs are presently evaluated annually by several observers to subjectively determine the ranking of the sheetings for cold cracking. After 31/2 years, it is apparent that Sunlite and 3M Engineer grade sheetings are performing considerably better than the other sheetings. Maclite is performing the worst of all sheetings, in fact, most of the Maclite signs have already been replaced tolerably, while the 3M Commercial grade sheeting is considered intermediate between Adcolite and Maclite. It has been found that there is considerably more cold cracking on plywood backed signs than on aluminum backed signs--regardless of the sheeting type. /Author/
