ABSTRACT

Libya suffers from the problem of the accumulation of asphalt waste resulting from road maintenance and reconstruction, which poses an environmental and economic challenge. This research paper aims to explore the possibility of recycling asphalt waste in Libya and examine the potential environmental and economic benefits of this process. Previous research indicates that old asphalt contains recyclable components that can be used in the manufacture of new asphalt. This requires remediation and crushing of the old asphalt before it can be reused. These processes can be performed using hot or cold recycling techniques. Waste asphalt recycling provides many environmental benefits. The extraction of natural raw materials used in producing new asphalt is minimized, reducing dependence on and conserving natural resources. It is also possible to reduce the amount of waste accumulated in waste sites, thus reducing environmental pollution. In addition, energy can be saved and carbon emissions can be reduced using recycled asphalt instead of new asphalt. Economically, recycling waste asphalt can reduce the costs of new infrastructure projects, as the price of recycled asphalt is usually lower than asphalt. In addition, the asphalt recycling sector can create new job opportunities and stimulate the local economy. This requires strong collaboration between the government, the private sector and the local community to implement these technologies and promote a culture of sustainability in Libya’s road infrastructure .
