Timely repairs of pavement defects are essential in protecting both public road and highway systems. Identification of pavement distresses is necessary for planning pavement repairs. This has previously been performed by engineers surveying the roadways visually in the field. As drone usage has progressed, it has become clear that drones are a valuable tool to enhance visual documentation, improve project communication, and provide various data for processing. The use of drone technology has improved both the speed and accuracy of capturing data. Available software has allowed the data to be processed and analyzed in an office environment. This report summarizes the use of drone technology for pavement evaluation for three case studies. Results from this study can be used to deepen understanding of drone use in the process of data gathering for timely repairs for transportation infrastructure.

LEROSE LANE, PE
Ms. Lerose Lane, PE, is a Senior Pavement Preservation Engineer who has worked for the California Pavement Preservation Center (CP2C) since August 2010. Her work includes observing pilot project construction for a wide variety of preservation strategies including: rubberized chip seals, scrub seals, reconstruction with rubberized hot mix asphalt concrete, and double chip seals. Besides observing and evaluating construction and long-term performance of a wide variety of preservation strategies, she co-authors many of the technical reports regarding the construction phases and follow up inspection reports. Most of these projects are Caltrans projects on state highways or interstate routes. She graduated from CSU Chico in 1970 with a B. S. in Civil Engineering. She has worked for the University of California, Davis; the City of Marysville; the County of Tehama; and Caltrans in various capacities including: District Materials Engineer, Office Chief in Design, Senior Construction Engineer, as well as a Resident Engineer for a wide variety of projects. She has been a Professional Engineer in the State of California since 1975.
