Asphalt Emulsion - an overview ScienceDirect Topics

Asphalt emulsion, as used in road construction and maintenance, is a homogeneous mixture of minute asphalt droplets suspended in a continuous water phase (Dybalski, 1976). The preparation of these oil-in-water (o/w) emulsions involves use of a high-speed, high-shear mechanical device, such as a colloid mill which breaks down molten asphalt into minute

An Introduction to Asphalt Emulsions Asphalt magazine

An asphalt emulsion is liquid asphalt cement emulsified in water. It is composed of asphalt, water and an emulsifying agent. The emulsifying agent is sometimes called the surfactant, which is composed of large molecules. These soap molecules are like tadpoles, having a hydrocarbon tail soluble in liquid asphalt and an electrically charged or ionic head soluble in water. The

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 stable suspension and controls the

Asphalt Emulsions 101 Asphalt magazine

An asphalt emulsion consists of three basic components, asphalt, water and an emulsifying agent. An asphalt emulsion is a stable dispersion of asphalt cement droplets in water, which can be pumped, stored and mixed with aggregates. An emulsion should “break” quickly upon contact with aggregate when mixed or after being sprayed. Breaking is the separation of the water

ASPHALT EMULSIONS – Asfaltos Emulsiones de Colombia S.A.S

ASPHALT EMULSIONS. Emulsions are given from the mixture of two non-miscible liquids, in this case, asphalt and water, thanks to a process of an aqueous phase and cationic emulsifiers that are capable of generating a variable stability that adjusts to the buyer’s need. Among the most popular are CRL-1, CRR-1, CRM asphalt emulsions. An emulsion can be defined as a

Tests on Bituminous Emulsions Controls Group

Asphalt emulsion is a dispersion of bitumen and water, with a cationic or anionic emulsifying agent. The bitumen content in the emulsion is around 60% and based on the mix stability, the emulsion can be Rapid Setting (RS), Medium Setting (MS), or Slow Setting (SC). Different types of emulsions require different tests; the most common are water content, setting time and

Investigation of rheological properties of asphalt emulsions

07/09/2021  The cost of cationic asphalt is lower than that of non-ionic asphalt emulsions and amphoteric asphalt emulsions. Cationic asphalt emulsions are widely used in engineering. Slow-cracking asphalt emulsions are more suitable for asphalt mixtures. Thus, rheological properties of cationic asphalt emulsions were studied in our study. A 60 ~ 80 grade asphalt
