Abstract

The durability of the retroreflecting materials High Intensity Grade (HIG) and Engineer Grade(EG) made by 3M, on signs in use at road construction sites, has been tested through periodical measurements of the coefficients of luminance over a period of use of two years. Both materials appear to age at the same rate.
