The ratio of hard asphalt powder to flux oil in the paving mix is about 1 to 4 down to 1 to 10, a common ratio being 1:5 to 1:8. Lighter viscosity flux oils, of course, will require more hard asphalt. A typical mix will be 1 gallon of liquid suspension (powder) to 2-1/2 gallons of S.C. flux. Typical flux oils have the following characteristics:

The main components of the emulsion are asphalt (bitumen) and water. Emulsions come in different grades but typically contain between 55 and 75 % asphalt. In addition to the asphalt and water, asphalt emulsions contain 0.1-2 % of an emulsifier or 'soap' which functions to stabilize the emulsion. These soaps are similar in nature to the ...

Cold mix asphalt is a mixture comprised of aggregate with a reduced viscosity asphalt binder [ 26 ]. It is produced by emulsifying bitumen in water prior to mixing with the aggregate at ambient temperatures [ 27, 28 ]. At the emulsification step, the bitumen is less viscous, the mix easier to …

The primary types of asphalt binders used historically in CMAs are asphalt emulsion or cutback asphalt. Asphalt emulsions are used in many different applications in road building including tack coats, prime coats, chip seals, and patch mixes. Asphalt emulsion is a dispersion of asphalt particles in water being held in suspension by an emulsifier.

Emulsified asphalt is known to produce minimal to no hydrocarbon emissions or fumes, as there is no need for hot mixing.
