OBJECTIVES: The primary objective of this study is to evaluate the performance of pavement markings currently being used in Kentucky and offer recommendations for application procedures and installation requirements. A secondary objective will be to conduct an evaluation of the raised pavement marker program in Kentucky. Results will include recommendations for the future use of raised markers as a roadway delineation device. BACKGROUND: Recent national research (NCHRP Report 518) has questioned the effectiveness of raised markers on two-lane roadways. Raised markers were first used in Kentucky in the 1970's with snowplowable markers used starting in the 1980's. The only statewide evaluation of the effectiveness of raised markers was conducted in 1981. Additional issues related to raised pavement markers include the installation procedures and overall durability. The Manual on Uniform Traffic Control Devices provides general guidelines for the application and installation of pavement markings. However, performance requirements for various types of pavement markings are not included. Kentucky's Standard Specifications for Road and Bridge Construction contain pavement marking materials composition specifications; however, performance measures have not been included. Project-specific performance measures have been included in some contract documents; however, this is not a standardized procedure. Installations of pavement markings have been observed to prematurely fail or deteriorate at an accelerated pace. Overall, there is a need to understand the useful life of various pavement markings including paints, thermoplastics, tapes, and raised pavement markers. A wide range of issues should be addressed, including material specifications, application procedures, useful life, and costs. FY 2007 PROPOSED WORK: The project work is expected to be completed and documented within the 2007 fiscal year. PROGRAMMED COST FY 2007: TOTAL ESTIMATED COST: $75,000 $75,000
