The slurry seal microsurfacing is a bitumen mortar made with highperformance binders and basalt aggregates that are coldapplied via a special selfpropelled machine. Ideal for correcting damaged paving. The main features of this treatment are considerably increased skid resistance, reduced braking distances, reduced aquaplaning risks and a consequent increase in safety.

aggregate such as granite, quartzite or trap rock (basalt)". Seal coats include a bituminous material meeting the specifications of MnDOT special provision 2356 and an aggregate which complies with MnDOT gradation and quality standards (2). Figure 2 shows a typical MnDOT seal coat surface treatment and application information.
The 5yearold slurry seal of has an average albedo of, ranging from to The 5yearold or more chip seal has an average albedo of, ranging from to The 3yearold or more cape seal (chip seal with microsurfacing on top) has an average albedo of, ranging from to
Slurry Seal is a cold mix blend of high quality crushed aggregates, asphalt emulsion, water and mineral fillers, mixed together according to a predetermined mix design from a laboratory. It is applied to an existing surface, such as surface treatment or pavements, that are still in fair to good condition, as a means of a cost effective ...
Microsurfacing (figure 10), while similar to a slurry seal operation, allows a thicker layer to be placed ( to thick) and cures faster than a slurry seal. Microsurfacing uses a polymermodified emulsion mixed with crushed aggregate, mineral filler (cement, lime, .
The combined aggregate shall conform to the gradation shown in the Table (A) when tested in accordance with ASTM C136.

Slurry seal is a mixture of aggregate, asphalt emulsion, water, and mineral fillers. Slurry seal is divided up into type I, II, and III. Each of the different types refers to the size of the aggregate in the slurry seal mix design. Type I slurry has 1/8" or smaller aggregate and is mainly used for parking lots.
emulsion sand slurry seal. Aggregate. The aggregate shall consist of sound, durable crushed igneous type stone (crushed basalt, granite, trap rock, etc.), clean washed masonry sand, or clean washed silica sand, be free from films of matter that would prevent thorough coating and bonding with the bituminous material and free
Aggregate/Bitumen Sealing Application Aggregate properties and the test methods specified in AS 2 Aggregate for sprayed bituminous surfacing – The requirements of AS 2009 A Primer Seal provides a light weatherproof wearing surface which allows the pavement to be trafficked early, sometimes immediately after construction.
Slurry Seal Vs Seal Coat. 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.

slurry surfacing and the pavement characteristics they improve are discussed next. Types of Slurry Surfacing There are two main types of slurry surfacing in common use. These include: • Slurry Seal • Microsurfacing Currently, Caltrans uses slurry seals routinely, while microsurfacing is still in the pilot stages of assessment.

Aggregates must be durable and clean to insure the asphalt bonds to the aggregate. Requirements will vary depending on the form of slurry (slurry seal or microsurfacing) and the type (A, B, C). Listed below are the laboratory tests used to check the aggregate for suitability in a slurry mix.

Slurry Seal Checklist 2 Project Review Verify that the project is a good candidate for slurry seal by confirming the absence of any alligator cracking indicative of subgrade failure or inadequate subsurface drainage. Investigate whether any rutting exists on the pavement, and if so, is ¼ in. or less in depth.

Purpose of a Slurry Seal A slurry seal is a thin surface treatment that is laid in a thickness equal to the largest stone in the grading of its component aggregate. It may include either a conventional or polymer modified emulsion, and the slurry seal may be slow or quick setting. The emulsion is usually cationic in nature, but may be ...
