Long lasting roads with “HI-GRIP” – The adhesion promoters cum anti stripping agent for the asphalt industry.
Adhesion promoters cum anti stripping agent based on our amine surfactant have been used for many years to enhance the bond between bitumen and aggregate in asphalt mixtures and other mixtures and other bituminous applications.
HI-GRIP provides clear evidence that amine promoters cum anti-stripping agent fortify the bond between bitumen and aggregate over the long term, thus giving a significant improvement in the durability of asphalt throughout its life.
The addition of the small amount of HI-GRIP adhesion promoter cum anti stripping agent to the binder, at little extra cost to the formulation, means road constructors and their clients can be assured that their asphalt pavements will have increased durability over the long term, and subsequent a longer life cycle.
Heat – stable adhesion promoter cum anti stripping agent for bituminous binders
HI-GRIP is a liquid additive, specially designed for hot-mixed asphalt where good heat stability is required. HI-GRIP may be stored in hot bitumen for up to 15 days at temperatures upto 170°C without significant loss of activity
The dosage of hi-grip depends on the type of bitumen and aggregate used. Normally between 0.2 and 0.5% is added to the binder.

The submitted material anti-stripping agent confirms to the standard requirement as given in Appendix-5, table A5 Of MORTH Specs 2001.
1. Additive Dosage : The dosage shall be determined depending on the nature (stripping value)of the aggregate and the size of aggregate. While the recommended minimum dose of anti-stripping agent for sprayed work is given in Table A5-2 (MORT&H) the actual dosage shall be determined in the laboratory as directed by the Engineer.
2. Mixing Procedure During Construction : The anti-stripping agent supplied in in liquid, solid, or concentrate form shall be thoroughly mixed with liquid bituminous material or with straight run bitumen. When used with straight, the correct dose of anti-stripping agent shall be mixed in a hot bitumen tank boiler.
The two constituents shall be agitated till the anti-stripping agent is thoroughly mixed. The dose of anti-stripping agent shall suitably be increased if the binder is to remain in bitumen boiler for a longer period.
Additive Dosage : the dosage shall be determined depending on the nature (stripping value) of the aggregate and the percent voids in the mix. While the recommended minimum doses for different types of bituminous premix materials in terms of void content are given in Table A5-3 (MORT&H) the actual dosage shall be determined in the laboratory as directed by the engineer.
