Gilsonite Sealer. Gilsonite Pavement Sealers. Gilsonite's proven properties make high-performance solvent-based and emulsion pavement sealers dry quicker, look better and last longer. As a natural antioxidant, it allows pavement sealers to stay blacker longer. Gilsonite's unique molecular fractions rejuvenate the pavement …
Slurry Seals Slurry seal is a mixture of aggregate, emulsified asphalt, water and additives that are properly proportioned, mixed and spread over a prepared surface. A polymer-modified system can be used in the same application and will enhance one or more properties of the slurry to better meet a particular project requirement. Slurry seal is
A slurry consists of a mixture of crusher sand of varying grading, water, a little cement and stable grade bitumen emulsion. The prime function of a slurry seal is to fill the surface voids to prevent further deterioration due to loss of stone through traffic action, or by ingress of water into the base.
The Latex-ite Airport Grade + Driveway Filler Sealer is a commercial strength, polymer modified asphalt emulsion-based low-VOC formula designed to beautify and protect your blacktop pavement. This non-skid sealer fills hairline cracks (1/8 in. or less) and is polymer fortified for added durability.

Modified slurry seal treatments are suitable low-traffic roads and can be applied using Type I and Type II aggregate. In addition to conventional and modified slurry seal, …
One product is a custom-made asphalt emulsion sealer fortified with up to 10% acrylic latex; the other is a blended product with 90% asphalt and 10% coal tar.
ASPHALT EMULSION: The asphalt used in slurry seal is emulsified before use and may be modified with a polymer. The emulsification process allows the asphalt to be pumped and mixed with aggregate at …
The International Slurry Seal Association defines a Slurry Seal as "placed at one stone's width thick". Micro Surfacing can be placed up to 1/2″ thick without a rut box and up to 1″ thick with a rut box. ... It consists of the application of a mixture of water, asphalt emulsion, aggregate (very small crushed rock), and chemical ...
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 …
P-631 should only be applied to unsealed asphalt or surfaces previously sealed with either Asphalt Emulsion or Refined tar-based sealers, not over surfaces sealed with gilsonite or other solvent-based seal coatings. Emulsified Asphalt Seal Coating (P-623) FAA Item P-623 is a specification for an emulsified asphalt spray seal coat, a polymer ...
The rural pavements are on a 7-year sealing cycle. Micro-surfacing. Micro-surfacing is a treatment designed to seal and restore pavement surfaces and to provide good skid resistance. It can be used to restore the cross-section of rutted pavements. Micro-surfacing is similar to slurry seal but is generally considered to be stronger and more durable.
Polymer-modified emulsified asphalt slurry seal shall consist of a mixture of a polymer-modified emulsified asphalt, mineral aggregate, water, and additives, proportioned, mixed and uniformly spread over a properly prepared surface as directed by the Buyer's Authorized Representative (B.A.R.). The polymer-modified emulsified asphalt slurry …
It is a mixture of polymer-modified asphalt emulsion, aggregate, mineral fillers, and water. This composition provides a strong bond and resistance to wear, rutting, and cracking. The polymer modification enhances the resistance to aging and improves the durability of the surface. ... On the other hand, slurry seal is a mixture of asphalt ...

After extended discussion and feedback from across the ISSA Technical Committee, Board members, membership, and the pavement preservation industry, we are releasing a new ISSA pavement preservation Guideline, "Recommended Performance Guideline for Polymer-Modified Emulsified Asphalt Slurry Seal, A115 - Provisional".
Binders are selected for the type of job. Binders may be emulsified asphalt or coal tar, emulsified polymer asphalt, latex modified emulsified asphalt, rejuvenating oil modified asphalt emulsions or hot applied binders with asphalt rubber fibers or polymers. VSS will advise on the type of seal that is suitable.
8.1.2 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 ...
