Emulsified asphalt is the most commonly used interlayer binder. However, in the process of use, emulsified asphalt will adhere to the phenomenon of construction vehicle tires. The interlayer bonding effect of emulsified asphalt is affected. Researchers have conducted a series of studies on this question [3-8].

Investigation of rheological properties of asphalt emulsions

That means that the asphalt emulsion with high solid content is more hard to flow. The viscosity of asphalt emulsions A-40, A-50 and A-60 were shown in Fig. 10. The viscosity of aphalt emulsions decreases with the increase in shear rate. Meanwhile, the viscosity of asphalt emulsions increases with the increase in solid content.

Tack Coat Guidelines - California Department of Transportation

Asphaltic Emulsion Asphalt emulsion consists of three basic ingredients: asphalt binder, water, and emulsifying agent. At times, other additives such as polymers are added. Polymers are either preblended with asphalt binder before emulsification or added as latex. Whenever the term emulsion is used in these guidelines, it means asphaltic emulsion.

Testing Asphalt Emulsions - Asphalt Emulsion Manufacturers ... - AEMA

Is there a test to determine the viscosity of a particular emulsion? Viscosity is defined as a fluid's resistance to flow. For asphalt emulsions the Saybol Furol viscosity test is used as a measure of viscosity. Depending on the type of emulsion, one of two testing temperatures are used, 25 o C and 50 o C (77 o F and 122 o F).

Basics of Asphalt Emulsions - Asphalt Emulsion Manufacturers ... - AEMA

The use of asphalt emulsions is growing and 10-20% of all asphalt is used in the form of asphalt emulsions. How are asphalt emulsions classified? Asphalt emulsions are classified into three categories; anionic, cationic, or nonionic. The anionic and cationic classes refer to the electrical charges surrounding the asphalt particles.

The Chemistry of Asphalt Emulsions

A typically acceptable emulsion-base asphalt using an optimum concentration of emulsifier provides an average particle size and distribution of 28% at <l micron, 57% at 1-5 microns and 15% at 5-10 microns as determined by photomicroscopy and the two electronic systems

About the Course. These test methods and practices, given under the headings titled Composition, Consistency, Stability, and Examination of Residue, cover the examination of asphalt emulsions composed principally of a semisolid or liquid asphaltic base, water, and an emulsifying agent. The course can be completed in about one hour.

Emulsion-Cutback-Spec-Test - Asphalt Institute

Emulsified Asphalt Analysis (AASHTO M140) Emulsified Asphalts are typically used as surface treatments and tack coats. They fall into four categories: quick setting, rapid setting, medium setting and slow setting. Emulsions can also be cationic and anionic. Depending on the type, several combinations of tests can be required to verify adherence ...

Open Access proceedings Journal of Physics: Conference series

A cold emulsified asphalt mixture is generally a mixture made of emulsified asphalt mixed with aggregate. Emulsified asphalt is manufactured of base asphalt, an emulsifying agent, and water, with approximate percentages of 40% to 75% asphalt, 0.1% to 2.5% emulsifier, and 25% to 60% water, plus some other minor components.

Waterborne Epoxy Resin–Polyurethane–Emulsified Asphalt: Preparation and ...

The viscosity variation and micromorphology of WEPEA were investigated, and the compatibility and stability of each component were verified. The results show that waterborne polyurethane can effectively improve the flexibility of emulsified asphalt with a high content of waterborne epoxy resin.

Definition and Properties of Emulsified Asphalt

Definition: A mixture of asphalt cement, water and emulsifying agent (free flowing liquid at ordinary temperature). These three constituents are fed simultaneously into a colloid to produce extremely small globules (5-10µ) of asphalt cement, which are suspended in water. The emulsion contain about 50% - 65% bitumen. Properties of Emulsified Asphalt

Additionally, trailing numbers are used to delineate the relative viscosity if the emulsion and the letters "h" and "s" indicate whether a hard or soft base asphalt is used to make the asphalt emulsions. Thus, a CSS-1h is a cationic slow set emulsion with a relatively low asphalt emulsion viscosity made with a hard base asphalt.
