Asphalt Emulsion Production. To create an asphalt emulsion, the asphalt and water are blended by a colloid mill, which uses spinning discs to break the asphalt up into droplets so it can be dispersed into the water. Some water droplets may also end up inside the asphalt droplets, making this a "waterinoilinwater" or double emulsion.

It displays a simplified version of the manufacturing process of asphalt emulsions using a colloid mill. In order to suspend the asphalt cement in water, it has to be sheared into microscopic droplets ranging from 1 to 10 microns. This can be accomplished with the aid of a colloid mill or a rotor stator. The process of shearing (or "cutting ...

There are several methods of producing pavement samples in the lab at the University of Arkansas. For asphalt concrete, these methods include gyratory compactors, a slab compactor, asphalt ing devices, an asphalt emulsion mill, and a rock crusher. For Portland cement concrete, three concrete mixers are available to cast laboratory mixtures.

In order to rectify issues related to rutting, the stiffness of the emulsion residue had to be increased. For this purpose, laboratory investigations were conducted on emulsion prepared with harder asphalt grade (VG30),, emulsion E4. Preparation of emulsion using colloid mill is difficult with VG30 because of its higher viscosity.

According to the emulsion of asphalt emulsion breaking speed can be divided into fast cracking, medium cracking and slow cracking type asphalt emulsion (Wang, 1985).Fast cracking emulsified asphalt has better results for spraying use in lower temperature conditions, mainly used for spraying, paving surface treatment pavement and penetration pavement (Wei, 2011).

Asphalt emulsion is a substance made up of water, asphalt binder, and an emulsifying agent. This mixture is composed of tiny asphalt droplets suspended in water. The emulsifying agent, usually a surfactant, keeps the asphalt droplets in a stable suspension, preventing them from coalescing. When the emulsion is applied to a surface and the water ...
