National Asphalt Day 2025

National Asphalt Day is celebrated annually on May 15th. This day, established by the Asphalt Institute, celebrates the many economical and efficient uses of liquid asphalt in roofing and paving. The Asphalt Institute introduced this annual observance in celebration of the members of their century-old trade association and the industry across the globe. The date also marks the founding of the Asphalt Institute in 1919. 

Studies show that 94 percent of all U.S. roads use asphalt and 80 percent of U.S. residential roofs use asphalt roofing shingles. This day increases awareness of asphalt roofing and paving products while demonstrating their resiliency and growing sustainability.

Asphalt’s resiliency shows through the product’s responsiveness to climatic conditions and natural disasters. Asphalt repairs roadways quickly after natural disasters and damage from weather-related events. Pavement designers use asphalt to better construct roads to withstand higher temperatures, snow, ice and extreme weather.

Asphalt road materials are recycled more than aluminum cans and newspapers in the U.S. The benefits of asphalt being the most recycled product in the U.S. include the environmental effects and the progression toward a more circular economy. The industry is committed to producing and constructing net zero carbon emission asphalt pavements in 25 years.
