modified bitumen
TSR value of asphalt should be more than 75%
AkaBit AD
The two primary components used to produce hot asphalt are bitumen and stone components, and how these two combine to generate asphalt affects how well asphalt pavement performs. These elements all interact with one another based on their unique physical and chemical properties. Cracking and stripping are the examples of damages that can come from a weak chemical interaction between bitumen and stone, separating the two elements from one another. Furthermore, these issues are made worse by the damaging effects of humidity and variations in the environment, such as hot weather and freezing periods. Damage from asphalt stripping is one of the primary issues that should be solved..
Generally, two types of aggregates are used in asphalt production, which include limestone and silica aggregates. Each of these types of aggregates has its advantages and disadvantages. The advantage of calcareous materials is their proper adhesion to bitumen, but the important thing that is very essential is the low mechanical resistance of this type of materials, which eventually causes damages to asphalt . On the other hand, silica materials have high mechanical resistance, which is an important feature for producing high quality asphalt. But the main problem of these materials is their weak adhesion to the bitumen. As a result, over time, it causes the aggregates to separate from the bitumen and many holes are created on the asphalt surface
In order to solve the problem of bitumen stripping, relying on modern knowledge and technology, we have been able to present a new product called Akabit AD, that increase the adhesion of bitumen to asphalt with a specialized formulation. This modified bitumen can increase asphalt TSR up to 15-25%. By improving the bond between bitumen and other components of asphalt, it prevents the penetration of water and moisture between the aggregate and bitumen in the asphalt, and as a result, ensures the moisture durability of the asphalt
