Gilsonite in Asphalt is used as an additive in asphalt and asphalt binder to build durable roads. making high-performance road surfaces only would be possible by Gilsonite because only special properties of Gilsonite will make this possible.

GILSONITE HMA GRADE FOR ASPHALT HOT MIX
Gilsonite as an asphalt binder modifier and because of its special properties will help to the Roads asphalts to have a better performance against the high temperature in countries that have warm weather and against deformation too.
when Gilsonite using in old asphalt modifying of roads will increase the life of old asphalt. By using Gilsonite in road asphalts the asphalt layer would be stronger and 20% thinner.
Gilsonite as an asphalt modifier can directly add to the hot mix plant with no additional equipment and it will give excellent bonding properties to Asphalt also will make it waterproof too and will Reduce the temperature sensitivity of asphalt.
GILSONITE AS PAVEMENT SEALERS
Gilsonite because of its properties will help the solvent of emulsion pavement sealers dry quicker, look better and last longer and will help the pavement sealers stay black longer and unique molecular properties of Gilsonite as well as its strong adhesion will make the sealer to be waterproof.
Making pavement with more lifetime will help the environment too and rejuvenating the used asphalt pavement of roads with Gilsonite will significantly save energy and will also ultimately reduce environmental damage and the use of natural resources.
As a result, we can briefly say that Gilsonite for use in asphalt pavement sealer has properties such as
- Superior appearance and weathering properties
- Perfect bonding properties
- pavement sealer stays black longer
- Asphalt will have water-resistance properties
GILSONITE WILL REDUCE ASPHALT COSTS
By using Gilsonite in Asphalt production big asphalt companies can reduce costs by about 13% the studies are showing that by using Gilsonite about 5% to 6% in bitumen as the raw material of Asphalt production would be equal to 24% of the consumption of other substances.
Some companies even use up to 8% of Gilsonite in the production of road asphalt to create more resistance to temperature change and deformation.
The Modified asphalt made with Gilsonite will have properties such as:
- Higher softening point and resistance for cracking.
- Better viscosity and elasticity also will reduce road cracking.
- Asphalt has a lower static and dynamic indentation
- Excellent performance at very low temperatures
