and even as adhesive. They are created by combining two substances that usually wouldn't mix (like oil and water) with an emulsifier. This makes a stable mixture that can be used in various ways.Common Asphalt Emulsions in the Industry: An example of a widely used asphalt emulsion is a tack coat. Tack is a light application of an asphalt emulsion designed to ensure a strong bond between asphalt pavement layers. This helps to prevent the slippage or delamination of a hot mix overlay from the underlying layer which can be caused by ...In contrast,

semi-solid form of petroleum used to bind aggregate together. A versatile material followed by a a layer of aggregate which is rolled and embedded into the emulsified asphalt. The process may be repeated to create a double or triple chip seal. Chip seals are used to prevent water intrusion into an pavement and create a high friction surface for safety. Chip ...A polyester reinforced asphalt emulsion roof membrane is most commonly used as a base layer for acrylic coatings such as #720 ARC ElastaHyde. With the addition of the #720 ARC ElastaHyde,

keeps the asphalt droplets in a stable suspension and controls the breaking time. The result is a liquid product with a consistency ranging from that of milk to heavy cream 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,
