With viscosities in the range 0.5–10 Poise at 60 C, an asphalt emulsion is of considerably lower viscosity than asphalt itself (100–4,000 Poise), allowing it to be used at a lower temperature. Low- temperature techniques for construction and maintenance reduce emissions, reduce energy consumption, avoid oxidation of the asphalt, and are less hazardous than techniques using hot asphalt.
K. Takamura, A. James, in Advances in Asphalt Materials, 2015220.127.116.11 Experimental confirmation of the stability diagram The stability of the bitumen emulsion produced from Athabasca oil sand (high-acid-number heavy crude oil) was studied as a function of NaCl and …
High-float emulsions have a quality, imparted by the addition of certain chemicals, that permits a thicker asphalt film on the aggregate particles with minimum probability of drainage. Some user agencies specify an additional cationic sandmixing grade designated CMS-2s, which contains more solvent than other cationic grades.
The National Cooperative Highway Research Program (NCHRP) is also studying the effects of rejuvenating agents on asphalt mixtures with high RAP and RAS binder ratios. Epps Martin, the principal investigator on NCHRP's Project 9-58, said, "We're evaluating whether higher recycled binder ratios up to 0.5 can be utilized if rejuvenating agents are used.

Asphalt emulsions are produced by dispersing tiny globules of asphalt cement into water treated with a small quantity of emulsifying agent. The dispersion takes place in a powerful blender, called a colloid mill, where spinning blades break or shear the liquid asphalt into suspended microscopic particles.

Polymer asphalt emulsions can be less brittle at low temperatures to resist cracking and stiffer at high temperatures to resist rutting and bleeding. Polymers permit the application of micro surfacing in wheel-path ruts and other locations where multiple stone depths are required.
Understanding Your Emulsions. Asphalt emulsions are used in many pavement preservation methods such as pothole patching, micro-surfacing, chip seal, fog seal, and crack filling, but keeping emulsion intact during transport to a job site can be critical to a successful result. Understanding the properties of the emulsion can make or break the
