Abstract

This article reports the results of a study based on a random sample of sharp curves in Georgia that were treated by the installation of raised and recessed reflectorized pavement markers. The random sample of study sites is representative of sites in moderate to warm climates where there is relatively little exposure to snow and ice removal operations. Results show that: (1) Recessed pavement markers outlast raised pavement markers by a factor of two or more under similar conditions; and (2) Over 95 percent of the recessed pavement markers remained in place for over five years on roads with up to an ADT of 4,700.
