Asphalt must be liquified before it can be pumped through pipes, mixed with stone aggregates, or sprayed through nozzles. Heating is one way to liquify asphalt for construction purposes. But when asphalt cools, it becomes a semisolid material. There are other ways to liquify asphalt for construction operations. One way is to emulsify it with an emulsifying agent and water. In the emulsification process, warm asphalt is mechanically milled into very very small globules (5-10 microns and smaller) and dispersed into the water treated with emulsigying agent. The emulsifying agent keeps the asphalt globules apart from one another and suspended in the water which allows the asphalt to be used at room and cold temperatures. After the emulsified asphalt is sprayed onto a surface or mixed with aggregates the water evaporates and leaves only the asphalt residue behind to cement the aggregates together or waterproof the surface it was sprayed on.
Cold Mix Asphalt is a mixture of aggregate and asphalt. Cutback asphalt is a liquid asphalt. Cold Mix Asphalt is a mixture of Aggregate and Asphalt. The Asphalt is usually am emulsion asphalt or a cutback asphalt. An emulsion asphalt is asphalt cement blended with water. Cutback asphalt is asphalt cement blended with a fuel oil, kerosene, or a naptha. The water, fuel oil, kerosene or Naphta evaporates and leaves the asphalt.
Aproximately 17.78 Sq Yds of asphalt @ 1" thick per ton. Aproximately 17.78 Sq Yds of asphalt @ 1" thick per ton.
superior performing asphalt pavement," is a pavement system designed to provide longer lasting roadways.
Depends on type and quantity of oil, but it tends to dissolve the bitumen binder and so destroy the asphalt.

asphalt plants that produce emulsified asphalt can recycle it so some will take it for free
Mix equal amount of CSS-1 emulsified asphalt with water at 30 degrees Celsius and after 15 minutes spray at 0.2 l/m2 at the surface prepared.
Hot mix asphalt is is heated for application, which thins the material. Remember those steaming metal buckets you used to see on industrial rooftops? Cold asphalt is liquified with something else besides heat. There are two kinds: Emulsified asphalt is mixed with water and an emulsifying agent. Think of it like salad dressing that does not separate in the bottle. The other kind is called Cutback asphalt and is mixed with a petroleum solvent such as naptha, gasoline, or kerosene. They both are liquids at ambient temperature when applied; then the solvent or water evaporates, leaving the asphalt behind. Look up at asphaltinstitute.org

I think when you see the machine ,you will see more clearly .The emulsifying effect depends on the emulsifier and agitator . From http://www.alliedtechltd.com/ ,you can see the machine .

There is a substantial amount of misinformation concerning the function and proper use of prime. Prime is not glue-causing the base to adhere to the pavement is not its purpose. Prime's purpose is to protect the base from rain and light traffic, when the paving will be delayed.A prime coat is an application of an asphalt cutback or emulsified asphalt to a prepared base. The base can be either a sub grade or a base rock. Prime functions as a protector from rain for both types of bases. A primecoat should not be confused with a tack coat. Tack is an a adhesive for gluing two asphalt layers together.
Asphalt is the correct spelling.
Use asphalt as a noun. I fell on the asphalt and hurt my knee.
