Retroreflectivity and Deterioration Characteristics of Sheeting Used for In-Service Guide Signs
To determine the deterioration characteristics of the retroreflective sheeting used for guide signs, this study examined 12-year (1998–2010) observation data on 230 guide signs located in a test square. On the basis of the data, the deterioration curves of sheeting materials were calculated and the mathematical deterioration model for retroreflective sheeting was accordingly constructed. In determining the most suitable reference model, we chose among a linear mathematic model, a second-order polynomial model, and a cubic curve regression model. It was then applied to the signs found along Jiangxi Yongwu expressway in China. This research is expected to provide guidance for the maintenance of traffic signs in our country.
