The race track of Azadi Complex underwent a complete renovation in 2013 and two types of asphalt, porous and SMA, were designed and implemented for this project by our team. Due to automobiles drift on the track, the asphalt is prone to rutting. Therefore, various bitumen and asphalt additives, including adhesion promoters, cellulose fibers, and polymers, were used in the asphalt. Now, after 11 years, the asphalt is still in use.
