Cutback Asphalt

A cutback asphalt is simply a combination of asphalt cement and petroleum solvent Like emulsions, cutbacks are used because they reduce asphalt viscosity for lower temperature uses (tack coats, fog seals, slurry seals, stabilization material)Similar to emulsified asphalts, after a cutback asphalt is applied the petroleum solvent evaporates leaving behind asphalt cement residue on the surface.

Asphalt Emulsion

Asphalt Emulsion Emulsified asphalt, as used by TxDOT, consists of asphalt droplets suspended in water This dispersion under normal circumstances would not take place, since everyone knows that oil and water don’t mix, but if an emulsifying agent is added to the water the asphalt will remain dispersed.

Asphalt emulsion

The $192,000 project - funded through the city's capital road fund and performed by Asphalt Maintenance of Eugene - will apply a protective coat of asphalt emulsion and sand on road surfaces to help prevent damage from normal wear, as well as improve surface friction for driving.

When is a Tack Coat Necessary?

All of the grades incorporate hard base asphalt The anionic grades are slightly preferred where limestone and dolomitic aggregates are exposed on the old road surface Cationic grades would be preferred for all other aggregate typ To meet the requirements of Table 702-10 the asphalt emulsion is diluted 50-50 with water.

EMULSION BASICS

seize or shear the asphalt emulsion • DO NOT apply severe heat to pump packing glands or pump casing The pump may be damaged and the asphalt may become even harder • DO NOT dilute rapid-setting grades of emulsified asphalt with water Medium and slow setting grades may be diluted, but always add water slowly to the asphalt emulsion.

Emulsified Asphalt

Emulsified asphalt is simply a suspension of small asphalt cement globules in water, which is assisted by an emulsifying agent (such as soap) The emulsifying agent assists by imparting an electrical charge to the surface of the asphalt cement globules so that they do not coalesce (Roberts et al, 1996 [1])Emulsions are used because they effectively reduce asphalt viscosity for lower.

Oil emulsions

An emulsion is a dispersion (droplets) of one liquid in another immiscible liqu The phase that is present in the form of droplets is the dispersed or internal phase, and the phase in which the droplets are suspended is called the continuous or external phase For produced oilfield emulsions, one of the liquids is aqueous and the other is.

Emulsion

An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable) Emulsions are part of a more general class of two-phase systems of matter called colloidsAlthough the terms colloid and emulsion are sometimes used interchangeably, emulsion should be used when both phases, dispersed and continuous, are liquids In an emulsion, one liquid (the dispersed.
