Roadbind is a brownish clear liquid at room temperature with characteristic citrous odour which is designed for use in Hot-Mix and Warm-Mix road constructions. This product is non-miscible with water and miscible with polar and hydrocarbon solvents due to its proprietary Fattypolyaminosilane chemical nature. This results in massive changes in chemical properties on paving bitumen of any grade (i.e VG-10, VG-30, VG-40, CRMB or PMB) as on addition, the bitumen becomes extremely receptive to aggregates and its bonding with aggregates becomes highly resistant to stripping even under extreme atmospheric conditions. However, it does not effect the physical properties of the treated bitumen like penetration, ductility, softening point etc. This ensures prolonged pavement durability without affecting the quality of work. The thermal stability of this product in hot bitumen at 1600C is over 15 days and no additional dose is required for pavement construction using Hot-Mix or Warm-Mix.
