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.Asphalt emulsions (emulsifi ed asphalts) are composed of asphalt particles suspended in water by use of a colloid mill, which shears the liquid asphalt in water. An added ... modifi ed. Nomenclature varies greatly depending upon the state agency or supplier. Federal, state and local agencies have used polymer modifi ed

Nomenclature can be a bit confusing and depends on the jurisdiction, but in Canada the treatments utilizing one-size stone (or close to one-size) are known as "chip seals". Seal coatings that use aggregate having a ...

Asphalt Emulsion. With Asphalt Emulsions, High Float = High Performer. Unlike conventional Bitumen emulsion, after the water evaporates, high floats leave more than just asphalt behind.. In the potentially bewildering "alphabet soup" of asphalt emulsion nomenclature, one term stands out: high float asphalt emulsion.. Asphalt emulsion may be designated RS, SS, QS, MS, C or AE; can be P, M ...Nomenclature and Terminology. James G. Speight PhD, DSC, in Asphalt Materials Science and Technology, 2016. 1.2.1.4 Asphalt Emulsion. Asphalt emulsion (emulsified asphalt), like cutback asphalt, is also designated as a liquid asphalt to distinguish this product from the typical semisolid to solid asphalt binders. It is a mixture of two normally ...

seize or shear the asphalt emulsion. • DO NOT apply severe heat to pump packing glands or pump casing. The pump may be damaged and the asphalt may become even harder. • DO NOT dilute rapid-setting grades of emulsified asphalt with water. Medium and slow setting grades may be diluted, but always add water slowly to the 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 Emulsion Mix (Cold): A mixture of unheated mineral aggregate and emulsified (or cutback) asphalt binder. It can be plant-mixed or mixed in-place. Asphalt Emulsion Mix (Warm): A mixture of asphalt emulsion and mineral aggregate usually prepared in a conventional hot mix asphalt plant at a temperature less than 95°C (200°F). It is ...In the potentially bewildering "alphabet soup" of asphalt emulsion nomenclature, one term stands out: high float asphalt emulsions. Asphalt emulsions may be …

Emulsion nomenclature is more complicated than any other binder nomenclature. Emulsion nomenclature describes the type, speed of break, viscosity of the emulsion, stiffness/hardness of the residue binder, and presence of any additives in this order. A "C" is the designation for cationic (positive charge) emulsions.Asphalt Emulsions . Emulsion ... Positively- Charged Emulsions are also classified into 3 types . Additional Nomenclature QS = Quick Set HF = High Float 1 = Binder residue = 60% Minimum 2 = Binder Residue = 65% Minimum h = Hard Pen Asphalt Base s = Soft Pen Asphalt Base or sometimes Solvent
