Laboratory foam asphalt plant

When hot asphalt (e.g., 150~160℃) encounters a very small amount of cold water (2~3%), a violent heat exchange occurs, causing the cold water to instantly vaporize and resulting in a "foaming" phenomenon in the asphalt. Asphalt exhibiting this "foaming" is generally referred to as foamed asphalt.

Description

Applications

When a small amount of cold water (2-3%) comes into contact with hot asphalt (e.g., 150-160℃), a vigorous heat exchange occurs, causing the cold water to instantly vaporize and resulting in a "foaming" phenomenon in the asphalt. Asphalt in this "foamed" state is generally called foamed asphalt. During the "foaming" process, the volume of the asphalt rapidly expands to several or even ten times its original size, and its viscosity significantly decreases, facilitating mixing with aggregates. Therefore, foamed asphalt is highly suitable for cold in-place recycling and warm mix asphalt technologies in road construction. Foamed asphalt technology originated in the United States, but with the implementation of China's Ministry-issued "Technical Specifications for Asphalt Pavement Recycling of Highways" (JTG F41-2008), foamed asphalt technology has also made significant progress and development in China.
