Slurry seal is a mixture of asphalt emulsion, fine aggregates and additives mixed and placed in one operation by a slurry machine. Slurry seal allows quick construction times and minimal disruption to the traveling public. The thin application is ideal for lower traffic areas such as residential neighborhoods.

The tensile and resilient characteristics of the mix were obtained at three different temperatures. The effects of emulsion con­ tent, curing, and vacuum saturation were investigated. The influence of add­ ing a small amount of portland cement was also evaluated. Finally, the properties of the emulsion mixture and asphalt concrete were compared.

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 ...

For asphaltic emulsion used as a tack coat, determine the following: RRm—the minimum residual rate of the tack coat specified in Section 39, "Asphalt Concrete," of the Standard Specifications. Note the different residual rates required for the various hot mix asphalt types and open graded friction courses.

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 ...

BASF is the world leader in the supply of styrene-butadiene rubber (SBR) for the modification of bitumen emulsions for cold mix applications. Nowadays we also offer hot mix asphalt (HMA) and warm mix asphalt (WMA) modifiers that can be used directly in the mixer of an asphalt mixing plant, e.g. rejuvenating agents, elasticizers or low viscosity additives.

The quantity of asphalt residue in the emulsion used in an open graded cold mix will affect the quantity of emulsion needed to hold the aggregate skeleton/mixture together. With a lower asphalt residue, more asphalt emulsion is required to achieve the desired effect. Also, the more viscous the emulsion is, the better the mix should perform ...

A mixture of: • asphalt emulsion • graded aggregates • mineral filler • water • Additives When placed on the pavement surface the mixture breaks and cures creating a new wearing surface. FRESHCURED – Chapter 8 Slurry Seals

Cold mix asphalt usually refers to an asphalt mixture obtained by mixing bitumen emulsion, aggregates and filler at ambient temperature [7]. By using cold mix asphalt, energy savings of 95% compared to HMA manufacturing can be achieved [4,5,8]. The disadvantages of cold mix asphalt …

Asphalt emulsions, used in road construction and maintenance, may be defined as an homogeneous mixture of minute asphalt droplets suspended in a continuous water phase. These types of emulsions are usually termed oil-in-water (o/w) emulsions. Their preparation involves the use of a high speed, high shear mechanical device, such as a colloid mill.
