What is ss 1 tack coat?

SS-1 is an anionic slow setting asphalt emulsion primarily used as a tack coat – typically providing that “glue” to bond an existing base pavement layer to a newly applied layer. SS-1 can also be used appropriately where coating, bonding and waterproofing may be required.

What is SS1 emulsion?

Hincol Bitumen Emulsion SS1 is used for Prime Coat application and perform several important functions such as coating and bonding loose mineral particles on the surface of the base, hardening and toughening the surface of the base, waterproofing the surface of the base by plugging capillary or interconnected voids.

What is rs1 emulsion?

Hi-Tech Emulsion RS-1 is specially designed water based with low viscosity and fast setting time that makes it an ideal product for spray application. It is chocolate brown in color and is a free flowing liquid at ambient temperature. Hi-Tech Emulsion RS-1 is manufactured strictly conforming to IS 8887:2004.

What is the difference between tack coat and prime coat?

Prime’s purpose is to protect the base from rain and light traffic when the paving will be delayed. A prime coat is an application of an asphalt cutback or emulsified asphalt to a prepared base. The base can be either a subgrade or a base rock. Tack is an adhesive for gluing two asphalt layers together.

How do you calculate prime coat amount?

Specific Gravity of Prime Coat= 0.95. Calculate increase in Weight= (B-A) kg. Rate of Spray in Kg = (Increase in Weight)/(Area of tray) Unit of Rate of Spray in kg/sqm.

What is the use of bitumen emulsion?

Bitumen emulsions are widely used in pavement preservation techniques such as chip seal, fog seal, and microsurfacing, which look to maintain the surface properties of the road while preserving the structural layers beneath.

Who are the manufacturers of asphalt sealing products?

Bonsal American produces all three products, as does GemSeal, SealMaster, Star Inc., Surface Coatings Co., and Vance Brothers Asphalt Mfg. & Supply.

Which is the best pavement sealer to use?

Coal tar might be the best, but contractors have other alternatives when it comes to pavement sealer. As sealcoating contractors begin their season many of them, particularly those accustomed to using refined coal tar sealer, wonder what the season will hold for their favorite product.

How big is a ss1h tack coat sprayer?

Most all sprayers will work. SS1H Tack Coat is thin and has an approximate density of 8.2 lbs per gallon. There is no aggregate in the material. The material will not clean up with water so a solvent will need to be used. Therefore the sprayer system must be able to withstand solvents to clean up.

How is sealing asphalt different with emulsion-based…?

Manufacturers agree that the first thing contractors need to realize is that 100% asphalt-based sealers are very different from coal tar sealers. “First of all, the material sealer producers buy to make asphalt-based pavement sealers is not produced with that purpose in mind,” says Tim Vance, president of Vance Brothers.
