Numerous experiments were carried out to investigate the high temperature performance and fatigue resistance of carbon black modified hot mix asphalt binder.
Hot Mix Asphalt
Hot mix Asphalt was changed using three different kinds of particle sizes and three different kinds of carbon black contents.
It has been discovered that adding CB can improve the overall performance of virgin asphalt binder in terms of rutting resistance and medium temperature fatigue.
However, at CB of 270 m and 2.6 m, its addition under certain contents resulted in a reduction in the asphalt binder's high temperature and fatigue performance.
The inclusion of CB reduces rutting resistance and increases fatigue resistance in old asphalt.
The suggested CB content and particle sizes are 2% and 2.6 m, respectively.
Hot Mix Asphalt Features
By providing a reference for calculating the size and amount of CB in asphalt modification, this work clarifies the intricate effects of CB on asphalt properties.
The primary type of freeway pavement is asphalt.
| Title | Description |
| Resistance | High |
| Suggested CB | 2% |
| Modifier | Polymers, Silica gel and Carbon Black |
| Effect of CB | Improve the Overall Performance |
Anti-deformation and anti-fatigue performance of asphalt pavement should be ensured in order to counteract the effects of vehicle load, age, and environmental conditions, and the performance of the asphalt mixture applied to the pavement is determined by the asphalt properties.
At the moment, altering asphalt is the major way to improve its qualities.
To modify asphalt in accordance with diverse requirements, a variety of additives are available, including polymers, silica gel, carbon black, carbon nanotube, resin, polyphosphoric acid, wax, and resin.
Buy Hot Mix Asphalt
More effective waste management is being carried out as a result of society's global awareness of the need for more sustainable development.
A lot of research has been done on the use of waste items as bitumen modifiers, in addition to increasing the bitumen's qualities, to lessen the quantity of the trash that ends up in landfills.
The bitumen modifiers polyurethane, ethylene vinyl acetate, and polyethylene are a few examples of waste products.
Each year, a lot of used tires are created due to the rise in automobile ownership.
These used tires can be disposed of in a number of ways, including landfilling, retreading, recovering materials, recovering energy, etc.
Alliotti spearheaded the use of CB for asphalt alteration after studying its features.

Hot Mix Asphalt Price + Buy and Sell
According to studies, adding CB improved the rutting resistance and crack resistance of the asphalt binder, as well as the softening temperature and storage modulus of asphalt.
It also boosted the mixture's strength and aided in promoting the mixture's healing.
The two primary areas of research on CB modified asphalt at this time are the dispersion of CB in asphalt and the impact of CB content on asphalt performance.
Although there is conflicting evidence, it is possible that CB's particle size, as a type of powder additive, may also have an impact on how well modified asphalt performs.
On average, a ton of hot-mix asphalt costs between $40 and $80.

The Answer to Two Questions About Asphalt
1: Is asphalt cheaper than concrete?
Asphalt costs $2 to $4 per square foot less than concrete, Asphalt prices follow crude oil prices, Concrete driveway installation costs $4 to $6 per square foot.
2: Does asphalt crack easily?
As temperatures rise and fall, moisture is drawn in and out of asphalt, increasing or decreasing its ability to develop cracks.
