microsurfacing vs slurry seal

Slurry seal vs seal coat—which of these sealing options is right for your road paving, asphalt driveways, parking lots or playgrounds? While the terms are often used interchangeably because both protect and extend the life of your asphalt surfaces, the two applications are different. It is important to identify and understand these differences before making […]

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.".

The Microsurfacing Process. 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.

Chip seals are placed under one of three scenarios, as a "wearing course" meaning vehicles drive directly upon it; as part of a "cape seal" meaning a chip seal is first placed, then covered by slurry seal or microsurfacing; or as an "interlayer" meaning a layer between underlying asphalt pavement and a new asphalt or rubberized ...

The difference, however, is slurry seals cure through a thermal process while microsurfacing uses a chemically controlled curing process .

a distinct advantage of mirco surfacing over a slurry seal is that micro surfacing hardens quicker than slurry seal, allowing it to be used when conditions would not allow the slurry seal to be successfully placed – on streets that have a lot of shade, streets that have a lot of stop and go or turning traffic, and streets where you need to get …

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.).

Small deformations and ruts can be corrected with slurry seals, more extensive ruts can be filled with microsurfacing. Slurry surfacing provides a quieter surface than chipseal (surface dressing), with a lower texture more receptive to road marking and less liable to snow plough damage, and without loose rock that can lead to wind-shield damage.
