ABOUT DUVAL ENGINEERING

John Duval, P.E.

John is a professional engineer with 20+ years of experience in the design and construction of highway and airport pavements. His career highlights include stints as an Air Force Pavement Team Leader and Asphalt Institute Engineer, positions that allowed him to develop expertise in pavement design and evaluation, materials analysis, construction quality control, and pavement preservation.

John began his career in the US Air Force and served as Chief of the Air Force Pavement Evaluation Team, directing a military engineering team in the technical evaluation of pavement systems at 30+ airfields in Europe, Asia, and the Americas.

As the Asphalt Institute Regional Engineer for 7+ years, John forged strong relationships with public works officials and asphalt producers in a nine-state region from Washington to Colorado. He provided direct technical assistance in support of highway and airport projects where he developed a reputation as a trusted source for understanding the “tried and trued” methods of construction. A wide variety of experiences over many years allowed John to become comfortable “pushing the envelope” with innovative methods for building better pavement structures.

John founded Duval Engineering LLC to fulfill his dream of working together with clients to improve the quality of pavement systems in roadway and airport applications. He continually strives to look for new ways to return the highest value to stakeholders and the traveling public.
