Kuwait suffers from potholes due to pavement deterioration when exposed to moisture. This paper investigates the feasibility of using recycled asphalt pavement in Hot Mix Asphalt design. Questionnaires were conducted to analyze the effects of pores on the society. The results of a series of laboratory tests, which compared the performance of both the recycled and the regular mixtures, showed that the recycled mixture has higher stability and flow, lower rutting depth for wet and dry samples, and lower voids filled with asphalt and voids in mineral aggregate. On the other hand, the tensile strength ratio test results recommended to reduce the proportion of recycled aggregate. While, the HWTD test required 20% reduction in the wet recycled mixture. Therefore, the recycled mixture reveals a higher efficiency in saving costs and improving mixtures used for potholes maintenance activities. All the results proved that the recycled asphalt mixtures are most preferred since they are affordable and perform reasonably well compared to regular asphalt mixtures. As a future work, smaller percentages of recycled aggregate should be tested to check the robustness and sustainability of the designed recycled asphalt mixture. Furthermore, more experiments can be run to test other mix parameters and properties.
