Shanghai Experience with Warm Mix Asphalt

Warm mix asphalt (WMA) technologies have been developed to mix, transport, pave, and compact asphalt mixture at temperatures up to 40°C lower than the conventional hot-mix asphalt (HMA). The benefits of WMA include energy savings, lower CO2 emissions, and reduced workers’ exposure to fumes, reduced binder ageing, and faster release of pavement to traffic due to shorter cooling time. Since it was introduced into Shanghai, China in 2006, WMA has been successfully used in more than 10 projects, including expressways and viaducts. The WMA in these projects performs well so far. This paper presents some of these WMA projects in Shanghai.
