New Asphalt Pavements for a New Century

This article describes how, as the Eisenhower National System of Interstate and Defense Highways makes its 50th anniversary, new durable asphalt pavement designs are revolutionizing Interstate and National Highway System pavements. A new generation of asphalt pavement design is standing up to unprecedented traffic loads and is changing how government transportation agencies specify hot mix asphalt (HMA) and how asphalt contractors place it. These new mix and pavement designs include, Superpave, the performance-driven asphalt pavement designs developed in the United States; the stone-matrix asphalt (SMA), a super durable design imported from Germany; polymer-modified open-graded friction course (OGFC) asphalt pavements, which reduce tire spray and attenuate pavement noise; the new Perpetual Pavements, an HMA pavement structure design that competes with portland cement concrete (PCC); and the new “warm” asphalt mixes, which will quell energy costs and reduce potential emissions. This article looks at how asphalt pavements are changing at the start of the 21st century.
