Across the globe, both local and national authorities recognize the advantages of incorporating modified asphalt into new road initiatives. This approach proves to be cost-effective over the short and long term, as it enhances road durability against rutting and cracking. Consequently, maintenance requirements diminish, alleviating both financial and traffic-related concerns since road closures during upkeep are minimized.

In contemporary road construction, the prevalent technique for bitumen modification involves the utilization of synthetic rubber known as SBS (styrene-butadiene-styrene). SBS originates from limited primary resources, thereby incurring not only economic expenses but also environmental implications. Nevertheless, the application of SBS as a bitumen modifier can be substituted with recycled rubber powder (Iran Rubber FINE POWDER). This substitution has evolved into a standardized practice, backed by years of practical implementation on a global scale.
