Abstract:

Pavement marking delineation is one method to provide positive driver guidance on all roadway types. There are a variety of pavement markings used by local and state transportation agencies in the United States. The type of pavement marking applied to a roadway surface is often a function of climatic conditions, funds available to apply and maintain the markings, and the anticipated performance of the markings. The Pennsylvania Department of Transportation (PennDOT) developed a program in 2005 designed to periodically collect pavement marking retroreflectivity data on longitudinal lines throughout the Commonwealth of Pennsylvania. The purpose of this program was to develop a comprehensive analysis database that could be used to create a pavement marking management system for both waterborne and durable (epoxy) pavement markings on a variety of roadway types. In order to develop a cost-effective pavement marking management system, the service life of pavement markings must be well understood. Consequently, the main objective of the present study was to estimate the service life of longitudinal pavement markings using pavement marking retroreflectivity data provided by PennDOT's Bureau of Highway Safety and Traffic Engineering. Various statistical models were specified to produce pavement marking degradation estimates that PennDOT can use to estimate re-stripe times for longitudinal pavement markings.
