1) This requirement shall be applicable only under situations where the ambient temperature is below 15℃.
2) The value of solubility is determined on distillation residue at 360℃

Features:

  • Penetrate the cracks & crevices and impart strength to the layers
  • Bonds well to cool, damp substrates/surfaces
  • Good penetration into miniature pores of sub bases
  • Low temperature curing
  • Extended breaking
  • Easy spray
  • Prevents permeability of atmospheric air to the bottom layer
  • High adhesive properties
  • Binds loose aggregates together strongly
  • Water resistant and enhances easy drainage of water
  • Prevents lateral movement of structural layers
  • Prevents raveling and rutting

Applications:

Prime Coat: Application of SS-2 to an absorptive surface, designed to penetrate, bond and stabilize this existing surface and to promote adhesion between it and the construction course that follows. Recommended rate of application is 6 to 9 kg per 10 sq. m.

Fog Seal / Crack Seal: Light application of SS-2 to an existing pavement as a seal to inhibit raveling, or to seal the surface, or both. Also used to fill and seal small cracks in existing pavements. Fog seal helps to rejuvenate an old oxidized road surface, thus extending its life. Recommended rate of application is 5 to 10 kg per 10 sq. m.

Slurry Seal: It is a surface treatment for structurally sound roads where the wearing course has deteriorated. Slurry seals are mixtures of fine aggregate, Portland cement filler, bitumen emulsions and additional water. When freshly mixed, they have thick consistency & can be sprayed to a thickness of 1.5 - 5 mm. They may be used to seal cracks, arrest fretting and fill voids and minor depressions. Recommended rate of application is 10 to 12 kg per 10 sq. m.

Premix Seal Coat: Premix is a mixture of fine aggregate, Portland cement filler, bitumen emulsions and additional water. They may be used to seal wide cracks, fill voids and minor depressions. Recommended rate of application is 10 to 12 kg per 10 sq. m.
