Abstract : A little attention has been paid on the quality of reflective sheeting used for road signs in the past. Moreover,
significant number of road accidents recorded during the nights, have been attributed to sign aging and accumulation of dirt
deposit. A research study was thus undertaken to evaluate the performance of different sign’s sheeting brands, grades and
color installed on national Highways (N-5) and Motorways (M-1 and M-2). The aim of this research study was to assess the
aging of sign sheeting. Laboratory and field retroreflective measurements of sign sheeting were taken with portable handheld
equipment retro-reflectometer at different orientations and observation angle.Aging Characteristics and impact of sign
cleaning were also studied in addition to sign life cycle cost analysis. It was noticed that Coefficient of retroreflectivity
varied greatly with Instrument rotations and observation angles. A linear trend in the rate of reduction of coefficient of
retroreflectivity with age has been observed in the field. Also, retroreflection improved by 13-20 % on an average for various
sheeting brands and grades maintaining the signs.
