Every Day Counts (EDC) is the Federal Highway Administration's (FHWA's) program to advance a culture of innovation in the transportation community in partnership with public and private stakeholders. Through this State-based effort, FHWA coordinates rapid deployment of proven strategies and technologies to shorten the project delivery process, enhance roadway safety, reduce traffic congestion, and integrate automation.

About half of all infrastructure dollars are invested in pavements, and more than half of that investment is in overlays. Targeted Overlay Pavement Solutions (TOPS) enhance overlay performance, helping agencies maximize their investment and ensure safer, longer-lasting roadways for the traveling public. Many of the pavements in the Nation's highway system have reached or are approaching the end of their design life. These roadways carry daily traffic that often far exceeds their initial design criteria. Overlays are now available for both asphalt and concrete pavements that will provide long-life performance under a wide range of traffic, environmental, and existing pavement conditions.


Tim Aschenbrener, P.E., is a Senior Asphalt Engineer on the Pavement Materials Team in FHWA's Headquarters Office of Infrastructure. His work and expertise focus on asphalt materials, recycled materials, and quality assurance. Tim joined FHWA in 2012 after working with the Colorado DOT for 22 years.

Robert Conway, P.E., CCM, is a Senior Pavement and Materials Engineer with the FHWA Resource Center. Prior to joining the Resource Center he served as the Division Project Oversight Manager and Pavement & Materials Program Engineer in the Michigan Division of the FHWA.
