Pavement markings play a significant role in the highway system by providing guidance and conveying regulations and warnings to road users. In Region 6, specifically in Louisiana, thermoplastic pavement markings are commonly used on construction projects. Yet, the field performance of thermoplastic markings is not well-documented, specifically in hot and wet climates experienced in Region 6. Hence, the objective of this paper was to quantify the field performance of thermoplastic pavement markings. To achieve this objective, retroreflectivity data for several thermoplastic pavement markings from the 2012 and 2015 national transportation product evaluation program (NTPEP) Florida test decks were retrieved. Retrieved data were analyzed to determine the service life of these markings using three different techniques: linear interpolation, linear regression, and piecewise linear regression. Results indicated that the predicted service life of thermoplastic pavement markings ranged between 0.3 and 8.1 years, with an average value of 3.6 years. This large variation in the service life could be attributed to the line color, traffic level, surface type, weather conditions, etc. The results of this study could be utilized in future research to develop pavement marking performance models that could predict the performance of pavement markings based on the project conditions without the need for monitoring the retroreflectivity of pavement markings.
