slurry seal vs micro surfacing

Microsurfacing is similar to slurry seal. It consists of the application of a mixture of water, asphalt emulsion, aggregate (very small crushed rock), and chemical additives to an existing asphalt concrete pavement surface. Polymer is commonly added to the asphalt emulsion to provide better mixture properties.

Micro-Surfacing. Micro-surfacing is composed of engineered, polymer-modified asphalt emulsions mixed with crushed well-graded aggregate, mineral filler, water and additives. The main difference between this system and slurry systems is that micro-surfacing is stackable and therefore engineered for rut fill applications and minor structural ...

Two slurry products can be distinguished - Slurry seal and microsurfacing. Slurry seal is normally laid no thicker than 1½ times the top size of the aggregate, which can range from 3-10 mm. Mineral fillers like cement or hydrated lime are commonly used, but are not always required. Slurry seals waterproof and seal the surface from water

Sealcoating vs. Slurry Seal. Sealcoating is a thinner mixture with smaller aggregates (or none at all). It can be sprayed or squeegeed on, curing in 2-4 hours to provide a smoother surface than slurry. Our paving experts recommend it for use in low traffic, low-speed areas like driveways and parking lots housing smaller, lightweight vehicles ...

The main purpose of slurry surfacing is to stop fretting of the pavement surfaces caused by loss or ageing of the binder, seal imperfections and repairs and provide an even, consistent running surface. Standard slurry seals/surfacing provide an excellent skid resistance for low speed traffic but because of their relatively low texture depth, micro-

"Quick-set" slurry seal can be opened to traffic within an hour and usually has a shorter mix time. Microsurfacing can be laid in multiple layers to correct significant deformations including rutting and is suitable for higher traffic or higher stress situations. Higher quality aggregate is required, and usually has a top size of 5-10 mm.
