Prime Coat

 

Prime coat is an application of a low viscosity bitumen emulsion on a compacted granular base course which penetrate into the base (>8mm). A prime coat performs several important functions as given below:

• Coats and bonds loose mineral particles on the surface of the granular base
• Hardens or toughens the surface of the base
• Waterproof the surface of the base by plugging capillary or interconnected voids
• Provides adhesion or bond between the base and the bituminous mixture

Primer shall not be applied during a dust storm or when the weather is foggy, rainy or windy or when the temperature in the shade is less than 100C. BitChem deals in SS1 which is manufactured strictly as per ASTM D-2397-20 for Prime Coat Applications

 

Tack Coat

 

Tack Coat is a light application of low viscosity liquid bituminous material like emulsion to an existing surface (bituminous/ cement concrete/ primed granular surface) to facilitate a bond between the surface being paved and the overlaying course. The tack coat is recommended for all types of overlays. BitChem deals in RS1, RS2, MS Grade, MS-High which is ideal for Tack Coat Applications manufactured strictly as per IS 8887:2018

 

Fog Seal

 

Fog Seal is defined as “a light application of diluted bitumen emulsion used primarily to seal an existing bitumen surface to reduce raveling and enrich dry and weathered surfaces. Fog Seal is a method of incorporation of bituminous binder to an existing pavement to improve its waterproofing characteristics, preventing further stone loss by holding aggregate in place, rejuvenating surface and improving the surface appearance. BitChem deals in SS1 which is manufactured strictly as per ASTM D-2397-20 for Fog Seal Applications.
