Application of 14,000-tonnes of warm mix asphalt (WMA) on a new highway near Strasbourg

In Europe, Eurovia and MeadWestvaco have been working together since 2006 in the development and promotion of warm mix asphalt (WMA). Since then, nearly one million tones of WMA have been manufactured and applied on different types of roads, under different climates, and with various types of aggregates and asphalt binders. This article describes one of the most challenging achievements realized thus far: use WMA in the construction of the three base courses on the highway A35, around the city of Strasbourg, France, near German border. The mix design incorporated 10% RAP - reclaimed asphalt pavement - materials with a 35/50 pen virgin binder. The average manufacturing temperature of the WMA was around 115°C, more than 50°C below the HMA reference. Construction of the WMA pavements began in November 2009, when ambient daily high temperatures were around 10°C. Job materials and mix properties are described. Production details, construction operations, and pavement performance characteristics are also presented. A comparison between the performance of the mix on the and in the laboratory is also discussed in conjunction with comparative performances of the HMA reference.
