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-
A cape seal is a combination of a single-chip seal application followed by slurry seal or micro-surfacing. The slurry or micro-surfacing application helps fill the voids between the chips. Coloured Slurry. Coloured slurry is a mixture of synthetic emulsion binder, pigments and specially selected aggregates. Uses include lane delineation ...
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 …
What is Micro-surfacing? Slurry Seal was expanded upon in the late 1960's and early 1970's in an attempt to use slurry in thicker applications that could be applied in narrow courses in wheel ruts to avoid not having to replace expensive traffic delineation on the autobahns.
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
Micro-surfacing is similar to slurry seal with the main difference being the liquid asphalt emulsion, which has added polymer modifiers to accelerate curing time and enhance durability. This enables the micro-surfacing to be used in heavy-duty or high-traffic volume situations. Micro-surfacing was originally developed for Germany's Autobahn and ...
Slurry seals cannot be used to correct surface profile (micro surfacing should be used instead), fill potholes, or alleviate cracking and should be used primarily on good condition pavement. Application rates for different aggregate types for slurry seals are shown in …
in the world. These self-propelled slurry seal and micro surfacing pavers optimize efficiency and reduce the number of construction joints, creating a smooth driving surface. They receive a constant supply of material from dedicated mobile support units while moving— making them ideal for all jobs, including those with strict quality ...
For this study, thin surface treatments, i.e., "microsurfacing," has been defined as any treatment less than ¾-1" thick which can be applied to the surface of an existing pavement with the objective of improving the performance of the pavement and ultimately
A slurry seal is a homogenous mixture of emulsified asphalt, water, well-graded fine aggregate and mineral filler that has a creamy fluid-like appearance when applied. Slurry seals are used to fill existing pavement surface defects as either a preparatory treatment for other maintenance treatments or as a wearing course.There are three basic aggregate gradations used in slurry …
Slurry Seal – A mixture of aggregate, emulsified asphalt, water, and additives properly proportioned, mixed and spread over a properly prepared surface. Slurry seal is applied in a single layer. It is generally used on low traffic primary and secondary roads. Micro-Surfacing (Latex-modified Emulsion Treatment) – A mixture of cationic
Slurry Vs. Micro | S3 Should there be a distinction? ¾Performance – Mix design method should simply show the benefit of one system over the other (e.g., rut filling capabilities, rapid vs. slow set) ¾Constructability – Issues are the same Team's recommendation: Slurry = Micro = Slurry Surfacing Systems (S3)
Seals and Reduces Pavement Oxidation 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. Corrects Rutting Issues
Micro Surfacing and Slurry Seals are cost-effective preservation treatments used to maintain and extend the service life of pavements and roadways. The International Slurry Seal Association defines a Slurry Seal as "placed at one …
Slurry Seal /Micro-surfacing Paver equipment is widely used in construction workmanship in common slurry seal, modified slurry seal and micro-surfaces. LMT5255TXF Slurry Seal /Micro-surfacing Paver Equipment The asphalt and aggregate can be sprayed together or respectively. It has some positive features including cost-saving, surface wear ...
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 ...
Slurry seals and micro-surfacing minerals can be mixed with different specifications of coarse and fine aggregates, mineral powder, etc. They can also be made of large-size stones, pebbles, and other multi-stage crushing. (b) Coarse and fine aggregates for slurry seal and micro-surface shall meet the requirements of Table 6.2.
Slurry Seal Applications. Slurry Seal is a black, durable, dust-free surface that fills in cracks and surface imperfections while offering excelling skid resistance for motorists. Slurry seal is great for resurfacing parking lots, roadways, highways, subdivisions, and more. Contact a Boxley office for additional applications.
Description. Mix designs are an integral part of the overall performance of Slurry Seal, Microsurfacing and Chip Seals. For mix design of Slurry Seals and Micros, there are several recommended sources including ASTM D3910, ISSA A-105 & ISSA A-143, and MS-19 Basic Asphalt Emulsion Manual.In the lab, blending of the materials that are to be used in the field is …
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 …
"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.
One of the most versatile tools in the pavement preservation toolbox, Micro Surfacing is a mixture of cationic polymer-modified emulsified asphalt, crushed aggregate, water, and other additives, properly proportioned and spread over a prepared surface. The special-purpose polymers and additives used in micro surfacing allow multiple stone ...

Microsurfacing has been utilized in the United States since 1980 as a maintenance treatment for pavement. This paper reviews the benefits, limitations, and factors that contribute to successful applications of microsurfacing. The history of microsurfacing, as well as a definition and process description of the treatment, is included. The body of scientific work on …
Micro-surfacing can be applied to multi-layer surfaces and in double applications. Therefore, micro-surfacing is most effective for heavy-traffic areas such as highways, freeways, and airstrips. How is Micro-surfacing different from Asphalt Slurry Seal? A few key factors make micro-surfacing different from slurry treatments: Micro-surfacing

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 ...
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.
