Pavement markings play a critical role in maintaining a safe and efficient driving environment for road users, especially during nighttime conditions. The Texas Department of Transportation (TxDOT) spends millions of dollars each year for installation and maintenance of pavement markings. In order to ensure that pavement markings remain effective, the highway agencies maintain them regularly by replacing the old markings. Therefore, selecting proper pavement marking materials (PMMs) that can maintain an acceptable level of functional performance over a longer period of time can lead to significant cost savings while maintaining safety. Thus, there is a need to evaluate the current performance specifications used by TxDOT and other users and to develop improved performance specifications reflecting the performance capabilities of existing materials. The overall objective of the TxDOT research project 0-5548 Development of Field Performance Tools and Program for Pavement Marking Materials was to develop a field performance evaluation program and to identify effective field evaluation methods and tools to improve the performance of PMMs. Advantages and disadvantages of different evaluation procedures were studied to design an effective program for evaluating and testing PMMs based on different external conditions, specifications, material selection criteria, and performance measures. As part of this project, field test decks were installed and data were collected. As a component of the project, a tracking database is developed. This document provides instructions and guidance to users of this tracking database.
