Model:LQ-AC001

I. Product Introduction

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 vaporize instantly, resulting in a "foaming" phenomenon in the asphalt. This "foamed" asphalt is generally referred to as foamed asphalt. During the "foaming" process, the asphalt rapidly expands in volume to several times or even ten times its original size, and its viscosity decreases significantly, making it easier to mix with aggregates. Therefore, foamed asphalt is very suitable for cold recycling and warm mix technologies in road engineering. Foamed asphalt technology originated in the United States. With the implementation of my country's Ministry-issued "Technical Specifications for Highway Asphalt Pavement Recycling" (JTG F41-2008), which simultaneously references AASHTO / CT-313 / BS-9228 (or customer-specified methods) in technical documents and lists the specific geometric and control parameters that the equipment must meet, foamed asphalt technology has made significant progress and development in my country.
