It is a persistent issue in our industry: a road is paved, and within a few years, it shows signs of significant wear. For a long time, the methods used to select an asphalt binder simply couldn't forecast how a material would behave under real-world pressures.
This is why our industry has moved to Superpave performance grading. We see this as an essential shift for any organization focused on building infrastructure that can withstand the demands of modern traffic and climate.
