persentage of cement in cold asphalt mix

Asphalt cement is the basic ingredient of asphalt emulsions. In most cases, it makes up from 50 to 75 percent of the emulsion. Some properties of the asphalt significantly affect the finished emulsion. But there is not an exact correlation between the properties

Because hot mix asphalt (HMA) is both costly and harmful to the environment, the use of cold in-place recycled (CIR) asphalt is important to highway pavement. But, because CIR pavement properties are not as effective as HMA, addition of additive materials to the mixture is required to improve the pavement characteristics. Effects of using nano-materials on the mechanical properties of CIR ...
