Knowledge-Based Firm in Iran Makes Asphalt from Crumb Rubber

“We succeeded in producing permeable asphalt which is made of waste materials like crumb rubber that allows water to pass through its surface,” Alireza Haddadi, the managing-director of the knowledge-based company, told ANA.

“The asphalt is designed based on the type and capacity of the road and the available possibilities, and then the type of asphalt is ordered to the production plant,” he added.

Haddadi noted that permeable asphalts produced by using crumb rubber are very efficient in Northern regions of Iran due to heavy and continuous rainfall, adding, “Water does not remain on the asphalt surface and is directed to the sides of the road which increases the safety of the road surface.”

“Designing asphalt by using crumb rubber plays a highly important role in preserving natural resources and the environment,” he added.

In a relevant development early this year, a group of researchers from a knowledge-based company in Iran had also provided a basis for reducing the number of road accidents by producing self-healing smart asphalt.

“In our company, we produced a new generation of smart bitumen through polarization method which can obviate the problems of the previously-developed bitumen,” said Massoud Alizadeh, the manager of the company.

“One of the important features of these asphalts is their self-healing property; since they enjoy a shape memory, they can return to their original status after a change and a possible failure,” he added.

Alizadeh described greater depth and durability as another feature of the knowledge-based product, saying that it is also more resistant to freezing and less slippery which decrease road accidents.

According to him, 100 tons of the product has been used in roads in Mashhad and other cities of Khorassan Razavi province in Northeastern Iran.
