Emulsified Asphalt – Pavement Interactive

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 ...

| AsphaltPro Magazine | How to Micro Surface

Although it may take up to four hours or longer for a slurry seal to cure enough to open for traffic, micro surfacing is designed to allow straight rolling traffic within one hour of paving. In addition to a faster curing time, the added durability that a polymer-modified emulsion offers makes micro surfacing an attractive option for busier roads.

Basics of Asphalt Emulsions - Asphalt Emulsion ...

Asphalt emulsion is a combination of three basic ingredients, asphalt, water, and small amount of an emulsifying agent. In the same process, these components are introduced into a mechanism known as a colloid mill, which shears the asphalt into tiny droplets. The emulsifier, which is a surface-active agent, keeps the asphalt droplets in a ...

Asphalt Emulsions 101 | Asphalt magazine

SS emulsions are designed for maximum mixing time and workability. They are the most stable emulsions and are used for tack or bond coats, fog sealing as well as in slurry seals and some asphalt surface courses. QS emulsions are designed for use in micro-surfacing and slurry seals when a quick curing time is needed for opening to traffic.

Cationic Emulsions – McAsphalt

Cationic Emulsions. There are three major classifications of emulsion grades: rapid-setting, medium-setting, and slow-setting. The terms "rapid," "medium," and "slow" relate to the amount of time it takes for the emulsion to cure and the amount of mixing that can be performed before the emulsion breaks.

Seal Coat and Surface Treatment Manual: Selection of Binder

After emulsion and aggregate have been applied to the road surface, the emulsion "breaks" leaving the asphalt cement holding the aggregate. The rate at which the asphalt globules separate from the water phase is referred to as the "breaking" or "setting" time.

Tack coat- Bitumen Emulsion for tack coat- Asphalt ...

Another secondary factor is the environmental conditions at the time of paving. If an asphalt emulsion is used for the tack coat, and if the humidity is very high or the ambient temperature is very high, the emulsion setting and curing time will be extended. The same is …

Curing Rates for Asphalt Emulsions

The curing rate of asphalt emulsions is related to the rate the emulsion gains shear strength. Numerous early failures with surface treatment applications are attributed to poor adhesion between the asphalt binder present in the emulsion and the aggregates. Asphalt emulsions are designed to lose water with time and thus develop enough adhesion ...

Asphalt Seal-Coat Treatments

Asphalt emulsions use surface-active agents or surfactants to suspend the asphalt particles in water. These surfactants or emulsifying agents are similar to soap, allowing the minute asphalt particles and the water to form a uniform mixture. When the asphalt emulsion is applied to the roadway, the asphalt cement and the water separate.
