Type 8 – Highway Signage, Construction Zone Devices, and Traffic Delineators (more commonly used sheeting than type 7)
Type 8 Retro Reflective Sheeting – Super high intensity prismatic retro-reflective sheeting having the highest retro-reflectivity characteristics (along with Type 7) at LONG and medium road distances. (see RA values of Table 2 at 0.1° and 0.2° observation angles) This sheeting is normally an unmetallized air backed micro-prismatic material. Typical applications for this material are permanent traffic signage, construction (work) zone devices, and highway delineators.
