Intelligent Paving and Rolling Construction Technology of Asphalt Pavement

The asphalt paving process

Language: English The Challenge At the outset the asphalt paving process seems to be simple. Trucks deliver hot mix asphalt from plants to the construction site. There the asphalt is loaded on asphalt pavers that evenly spread the asphalt. Finally, compactors compact the asphalt to its required density. Despite this relatively structured process our research shows that there are significant dis...

Stone Mastic Asphalt Pavement Technology for the New Millennium

Since the 1960s, Stone Mastic Asphalt (SMA) pavement surfaces have been used successfully in Germany on heavily trafficked roads. Because of its excellent performance characteristics, road authorities in Germany as well as major European Countries quickly adopted SMA as a standard wearing course. As a consequence of an asphalt study tour in Europe of an American delegation in 1990, SMA test sec...

Infrared Thermography Revolutionizes Hot-Mix Asphalt Paving

Hot-mix asphalt (HMA) surfaces comprise about 90% of the highways and roads in the U.S. Highways and are typically engineered to last 15 years or more, but many have been failing early due to potholes, cracks, raveling, and other problems. This premature road failure unnecessarily wastes millions of taxpayer dollars every year. This paper describes a series of research studies that were conduct...
