This　paper　introduced　the　situation　of　recycling　of　old　bituminous　concrete　abroad　and　also　analyzed　the　situation　of　that　in　China　briefly.　An　old　asphalt-mixture　highway　in　Beijing　with　about　10　years　history　was　chosen　and　recycled　as　hot　asphalt　mixture.　By　through　crushing,　sieving　the　old　materials　and　extracting　the　old　asphalt,　the　performance　of　old　asphalt,　such　as　penetration　index,　deformation　point　and　ductility　index　of　old　asphalt　was　determined.　Through　on　indoor　experimental　analysis,　the　design　method　of　the　mixed　proportion　of　the　recycled　bituminous　concrete　was　investigated　and　then　the　performance　of　recycled　bituminous　concrete,　such　as　high-temperature　stability,　low-temperature　crack　resistance　and　water　stability　etc.　was　determined.
