The objective of the study is to evaluate the performance of porous asphalt using waste recycled concrete material and explore the\neffect of adding Gilsonite to the mixture. Asmany as 90Marshall specimens were prepared with varied asphalt content, percentage\nof Gilsonite as an additive, and proportioned recycled and virgin coarse aggregate. The test includes permeability capability and\nMarshall characteristics. The results showed that recycled concrete materials seem to have a potential use as aggregate in the hot\nmix asphalt, particularly on porous hot mix asphalt. Adding Gilsonite at ranges 8ââ?¬â??10% improves the Marshall characteristic of the\nmix, particularly its stability, without decreasing significantly the permeability capability of the mix.The use of recycled materials\ntends to increase the asphalt content of the mix at about 1 to 2% higher.With stability reaching 750 kg, the hot mix recycled porous\nasphalt may be suitable for use in the local roads with medium vehicle load.
