8.2.1 Asphalt Emulsion Asphalt emulsions are defined in Chapter 2 of this guide as dispersions of asphalt in water advisory stabilized by a chemical system. In the case of slurry surfacing, the emulsion may be cationic or anionic; however, cationic emulsions are the most common. Caltrans Standard Specifications Section

A slurry seal is the application of a mixture of water, asphalt emulsion, aggregate (very small crushed rock), and additives to an existing asphalt pavement surface. A slurry seal is similar to a fog seal except the slurry seal has aggregates as part of the mixture. This combined mixture of the emulsion and aggregates represents "slurry.".

Cape seal treatment means building a protective wear-resistant layer on chip seal by slurry paver with micro-surfacing and chip sealing technology. It provides a compact surface that protects the aggregate from falling off and extends the road's service life.

Polymer-modified technology is used in asphalt emulsions to improve physical properties, performance, and durability. Our polymer-modified asphalt emulsions provide an increased service life and life-cycle-cost savings. They can be used in applications that are unsuited to conventional asphalt emulsions or cutbacks.

OptiPave is an asphalt-based emulsion pavement surface seal designed to seal and protect asphalt roads while replenishing the pavement binder that is lost through oxidation and weathering. OptiPave beautifies, protects, and extends the service life of asphalt pavement while providing a rich, black, "like new" appearance.

A thin mixture of aggregate, mineral filler, and asphalt emulsion placed with a slurry surfacing machine. A slurry seal is a surface treatment that can be used to correct surface deficiencies and increase skid resistance. Slurry seals are a mixture of asphalt emulsion, aggregate, mineral filler, water, and other additives. The fine

The asphalt emulsion used in microsurfacing contains chemical additives which allow it to break without relying on the sun or heat for evaporation to occur. Thus, microsurfacing is an application that hardens quicker than slurry seals and can be used when conditions would not allow slurry seal to be successfully placed.

Slurry surfacing systems (Slurry seal and Microsurfacing) are thin emulsion cold mixed overlays which are recognized as cost-effective restorative and preventive maintenance techniques for roadways of most traffic levels, airport runways and taxiways, highways, shoulders, sidewalks, foot

time in slurry seal and microsurfacing emulsions and mixtures. An experimental design was developed to study zeta potential as a function of important asphalt emulsion formulation parameters: the pH of the emulsifier solution, emulsifier dosage in the continuous phase, and temperature of the asphalt emulsion while measuring zeta potential.

George C. Wang, in The Utilization of Slag in Civil Infrastructure Construction, 2016 10.3.2.2 Slurry seal. Slurry seal is a mixture of well-graded fine aggregate with mineral filler and dilute asphalt emulsion.A single course is usually applied in thicknesses of 3–6 mm (1/8–1/4 in.). Slurry seals are effective in areas of excessive oxidation and hardening of the existing asphalt and are ...

Slurry sealing is a cost-effective treatment that will seal the pavement surface, fill small top-down cracking and restore surface friction. It is suitable on a variety of asphalt pavement types experiencing various levels of traffic, from highways to residential streets. …
