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 ...

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.".

Micro surfacing is a polymer-modified cold-mix paving system that can remedy a broad range of problems on today's streets, highways, and airfields. Micro Surfacing was pioneered in Germany in the late 1960s and early 1970s. German scientists began experimenting with the conventional slurry to find a way to use it in thicker applications …
The difference, however, is slurry seals cure through a thermal process while microsurfacing uses a chemically controlled curing process . Since the use of a polymer-modified binder results in more stability, microsurfacing can be placed in multistone thicknesses, unlike slurry seals. Due to this thickness, more powerful mixers are …

The only real downside to micro-surfacing is its cost, which is a bit higher than slurry seal because of the chemicals added, and those costs can add up if you apply multiple layers. Some estimates have …
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
413.1.1 Description. Micro-surfacing is a slurry seal that uses a polymer-modified emulsion binder, a high quality dense graded aggregate, mineral filler, water and other additives, properly proportioned, mixed and spread on a paved surface. The filler can be Portland cement, hydrated lime or other approved materials.
Slurry systems are pavement preservation surface treatments that encompass micro surfacing, slurry seal, and polymer modified slurry seal. Each treatment type is designed to extend the life ...

Slurry seals are classified into three types. Type I: Fine aggregates with diameters less than 2.36mm, commonly used in low-traffic areas, such as bicycle paths and walkways. Type II: Aggregate particles …
Slurry seal is typically one stone thick, or less than 0.25 inch, whereas micro surface treatment is typically placed at several stone thicknesses. Although polymer-modified asphalt emulsion can be …
Section 37 Bituminous Seals 4-3701 General.

Process. A cape seal is a process that includes placing a chip seal on the existing surface and then after a few days placing a slurry seal or micro surfacing layer on top of the chip seal. To place the chip seal, an asphalt distributor provides application of the binder to the pavement surface. A chip spreader immediately applies a uniform ...
Slurry Seal Advantages: Approximately 70% cost savings to hot-mix asphalt overlay. Lasts about 3X longer than conventional sealcoating. Fast Application & Curing Time. Single-pass will fill cracks, surface voices, and patches. Tough, durable surface free of dust and loose aggregate. Crisp black color and consistent texture for curb appeal.
The slurry seal must build sufficient cohesion to resist abrasion due to traffic. Otherwise, it will ravel off quickly, particularly in high stress areas. Early stone shedding is normal, but should not exceed 3%. General rule of thumb for a slurry seal is that it can be opened to traffic when it has turned black.

Micro-surfacing is similar to a slurry seal except it requires a more advanced polymer modified asphaltic emulsion, a more durable fine aggregate, and a chemical additive. The major difference between slurry seal and micro-surfacing is in how they break or harden. Slurry seal relies on evaporation of the water in the asphaltic emulsion.
Micro surfacing involves the placement of a polymer-modified slurry mixture consisting of dense graded aggregates, asphalt emulsion binder, mineral fillers, additives and water onto the existing pavement. Micro surfacing applications typically have a surface life of up to 10 years or longer, and they help improve skid resistance.
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.
Microsurfacing is presently the only type of bituminous slurry surfacing applied in Australia with slurry seals having not been used for many years. The guideline and model specification therefore solely provide information on the application of microsurfacing.
There are cost savings to be gained as well. Rather than spend $375,000/mile on major rehabilitation, you instead spend $10,000/mile on distress repair, have two micro-surfacing treatments spread out over a several-year period each at $50,000/mile, and many years down the line the surface would then need minor rehabilitation at $250,000/mile bringing …
A Cape Seal is a chip seal covered with a slurry or micro-surface. The benefits from using a cape seal include a very smooth surface with an increased durability by sealing the subbase. Often the use of a chip seal is not popular with the public because of the rougher ride and loose stones. With the addition of the top treatment, a slurry seal or micro …
