Microsurfacing. Microsurfacing is an advanced form of slurry seal that uses the same basic ingredients (emulsified asphalt, water, fine aggregate and mineral filler) and combines them with advanced polymer additives. Figures 1 through 4 show a microsurfacing slurry seal project.

Microsurfacing: Myth vs. Fact - Geneva Rock Products

Myth #1: Microsurfacing is just another name for slurry seal. Fact: Since micro surfacing sets up quicker than slurry seals and does not rely on evaporation, it can be used in conditions that slurry seals cannot be. Myth#2: Micro surfacing will make a road slick and ruin its surface texture. Fact: Specified with high-quality, durable aggregates ...

Microsurfacing - Transportation | seattle.gov

Microsurfacing is a process similar to a slurry seal. A mixture of asphalt emulsion and aggregate (crushed stone, gravel and sand) is applied to the road. However, unlike a slurry seal, microsurfacing uses emulsion that is modified with polymers and other ingredients so it cures more quickly. As shown in this short video, as the microsurfacing ...

Slurry Seal Treatment Types

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.".

Slurry Seals vs. Microsurfacing – What's the Difference ...

Jul 10, 2020· Microsurfacing doesn't need evaporation. The asphalt emulsion used in microsurfacing contains chemicals that allow it to break without relying on the sun or heat to cause evaporation. Microsurfacing, therefore, hardens quicker than slurry seals and can be used when weather conditions do not allow the slurry seal to be successfully placed.

microsurfacing and slurry seal emulsions is crucial to achieving this rapid break. The primary objective of this study was to investigate if zeta potential could be useful as a measure of emulsion stability and set time in slurry seal and microsurfacing emulsions and mixtures. An experimental design was developed to study zeta potential as a

Slurry Seals | Microsurfacing Contractors, LLC

Slurry seal was developed in the 1930s and improved with technological developments in the 1960s. Slurry seal is a more true "sealer" for asphalt pavements. It has a higher asphalt content design and is not used on thick applications. The main difference between slurry seal and micro-surfacing is that slurry seal uses a standard asphalt ...
