Gilsonite HMA

Gilsonite HMA in asphalting helps to increase the stability of asphalt and creates high adhesion between macadam and bitumen. This adhesion prevents the asphalt from cracking and also prevents plants from growing in the asphalt.

One of the most important things they do in asphalting is to reduce the thickness of the asphalt and reduce the amount of bitumen consumed. Another action that occurs in asphalt in the summer is the soft temperature that does not loosen or soften when mixing with asphalt due to sun exposure and Heavy trucks do not roll or fold when braking.

Most airports in the world prepare asphalt with the addition of Gilsonite HMA grade. the most important reason is during the heating time, when the airplane wheels collide with the airport runway and the asphalt does not change shape in summer and winter.

Gilsonite is a mineral material or dried bitumen, which is often used for Asphalt, and its color is black and shiny. Gilsonite is a material that is highly hydrophobic and has a high resistance to acid and base, and is mostly used to produce asphalt, because the solubility of Gilsonite in non-polar solvents such as molten bitumen, and on the other hand, it has good penetration and resistance. It has caused it to be welcomed by the asphalt and road construction industries.

One of the advantages of natural bitumen or Gilsonite for asphalt paving is that it increases the durability and life of asphalt, as a result of this advantage, it reduces the costs caused by the repair and maintenance of asphalt roads and the usual life of asphalt is between 2 It has increased 5 times.

Gilsonite increases the viscosity of asphalt, and because of this, unlike other asphalts, it makes the road more resistant to deformation caused by high temperatures. The use of Gilsonite plays an important role in asphalt recycling, which makes it possible to use old asphalt and is also the reason that recycled asphalt has the same resistance as new asphalt.
