MICRO SURFACING 410 Micro Surfacing 410.1 Description This section covers the materials, equipment, construction and application procedures for placing Micro Surfacing material for filling ruts and for surfacing existing paved surfaces. Micro Surfacing is a mixture of a latex-modified asphalt emulsion, crushed mineral aggregate screenings ...
Micro-Surfacing is a polymer modified cold-mix paving system that can remedy a broad range of problems on streets, highways, and airfields. Micro-Surfacing begins as a mixture of dense-graded fine aggregate, asphalt emulsion, water, and mineral fillers. It is applied to existing pavements by a specialized machine, which carries all components ...
What is Micro-Surfacing? One of the fastest growing, most cost effective ways to prolong pavement life and provide a safe traveling surface is a process called Micro-Surfacing. Micro-surfacing applies a durable, polymer-modified asphalt seal to roads that have begun to show signs of aging and minor distress.
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 …

Micro surfacing (also referred to as 'micro asphalt', 'micro' or 'thin surfacing') is a 'surface treatment' for roads. It is laid over the top of the existing surface to seal and protect it. It consists of a water-based mix of stones and bitumen which is spread over the existing surface by a special
Micro Surfacing has been a reliable pavement preservation tool in the United States since the 1980s. It is a high-performance slurry seal that extends the life of pavement by combining a polymer modified asphalt emulsion, water, mineral fillers, and dense graded fine aggregate.
Both slurry seal and micro surfacing are specifically-designed mixtures of asphalt emulsion, aggregate, water, mineral filler and additives, mixed in set proportions, and uniformly spread across a prepared surface. Slurry seal is about one stone thick, just under ¼ of an inch or smaller, while micro surfacing is usually applied at multiple ...
Micro-paving overlay custom mixed to job-specific conditions. A quick-set system that is traffic ready in a matter of hours. Surface preparation includes crackfilling and protection of utilities. Overlay spreader screed controls allow side-to-side and vertical adjustment to accommodate surface variations
What is Micro Surfacing Micro Surfacing is a mixture of polymer modified asphalt emulsion, mineral filler, water and other additives, properly proportioned, mixed and spread on a paved surface in accordance with a specification and as directed by the Buyer's Authorized Representative. Micro-Surfacing is one of the most versatile tools in road ...
Asphalt emulsions are defined in Chapter 2 of this advisory guide as dispersions of asphalt in water stabilized by a chemical system. In the case of slurry surfacing systems (like slurry seal and microsurfacing), the emulsion may be cationic or anionic; however, cationic …
Micro-Surfacing application is plastic deformation or pushed up asphalt on the surface. Here is an example where the surface lift has pushed up at the edge line. Once again the Micro-Surfacing material does a good job of filling in any low spots in the surface but it is not very effective when used to correct high areas in the road.
Asphalt oxidation causes major changes to binder properties and is a major contributor to age-related pavement failure such as fatigue cracking. The additional 3/8″ surface provided by micro-surfacing adds a new, protective layer to the pavement.
Micro asphalt is a form of highway surfacing used in highway preservation. It is made up of a mixture of aggregates and bitumen emulsions and acts as a replacement for hot asphalt, with the advantage of being laid thinner. Micro asphalt features all the well-known characteristics of a hot asphalt…
Micro-Surfacing includes polymer modified asphalt (key in flexibility), aggregate, mineral filler, additives and water. Micro's effectively seal, level, rejuvenate, and aid in skid resistance on existing paved surfaces. Micro-Surfacing can be applied in a wide range of thicknesses, allowing it to treat a large variety of road surfaces.
Problem. By itself, microcracking is only a small detriment to pavement performance; the cracks are usually quite shallow and small. However, microcracking can indicate mix tenderness, which can eventually lead to inadequate compaction either because (1) the mixture shoves rather than compacts under roller loads or (2) in an effort to avoid checking rollers are left off the mat so long that ...
Las Vegas slurry seal - Slurry seal was invented in Germany in the early 1930s as a new technique to cost-effectively maintain roadways. In the late 1960s, German scientists began experimenting with conventional slurry seal to help with the wheel ruts on the autobahns. By introducing different polymers, emulsifiers and better aggregate, microsurfacing was born.…

Advantages of micro-surfacing for asphalt roads include: Cost effectiveness: micro-surfacing costs are approximately one-third the costs of a pure blacktop overlay and, while slightly more expensive than a slurry seal or a tar and chip, it produces a far better product than both for blacktop roadways.
Slurry Seal – Pavement Surface Treatment. Slurry seal is a cold mix paving system that can remedy a broad range of problems on streets, airfields, parking lots, and driveways. Think of Slurry Seal as an Industrial Grade Asphalt Surfacing. The principal materials used to create slurry are aggregate, asphalt emulsion, and fillers which are ...
Micro surfacing is a surface treatment designed to extend the life of asphalt pavements in good condition by providing skid resistance, restricting moisture intrusion, protecting the structure from further oxidation and raveling, and restoring a uniform black appearance.
There are numerous causes of asphalt cracking. These include harsh weather or climate conditions, drainage problems, incorrect or poor quality materials, and traffic loads. Proper identification of crack type and cause is vital. Each type of crack has distinct causes. Timely maintenance is critical to keep asphalt conditions from deteriorating further. Here are 7 types …
The average total thickness of the Micro-surfacing should be of 10- 12mm and the application rate between 15kg/ sq.m to 20kg/ sq.m covering both the regulating and the wearing course layers. The required layer thickness of the Micro-surfacing materials is followed as …
Micro asphalt surface treatment is a preventative maintenance treatment, used to seal the existing road surface, improve the texture and helps water evaporate. This type of surface treatment can prolong the life of a road by up to 10 years.
Asphalt micro-surfacing is a cost-effective, long-term commercial pavement resurfacing solution that is commonly used for parking lots. It is a polymer-modified, cold-mix paving treatment that delivers a brand new surface for existing commercial pavements.
Micro Surfacing systems are mixtures of a polymer-modified cationic emulsified asphalt, mineral aggregate, mineral filler, water and additives that are proportioned, mixed, and spread with a machine over a properly prepared surface. Micro Surfacing systems are used to restore and preserve the surface characteristics of pavements. Micro Surfacing may be designed to correct rutting, improve…
Micro-surfacing is generally used as a maintenance or surface treatment for an existing pavement with an asphalt concrete surface. As a surface treatment, it provides a skid-resistant surface. As a maintenance treatment, micro-surfac ing is also used to fill ruts. Micro-surfacing has been used on …
A. Micro surfacing provides a thin asphalt overlay/sealer that will fill in slight imperfections and give your street a uniform color and texture. Most importantly, it seals the pavement, thus preventing the infiltration of water, which is the most frequent cause of pavement failure. There is a residue (sandy grit) that remains loose on the ...
Microsurfacing is a protective seal coat which extends the life of pavement. It is a thin, tough layer of asphalt emulsion blended with finely crushed stone for traction. This is a cost-effective method to renew the road surface and seal minor cracks and other irregularities. This preventive maintenance process protects the pavement from ...
Micro asphalt surfacing was first pioneered in Germany during the 1970s and it now enjoys numerous applications such as tarmac driveways, major road surfacing and even repairs associated with runways. It is also known as a "cold-mix" paving system due to the fact that it can be applied to an existing surface without requiring a great deal ...
