Improving　the　anti-ageing　performance　of　bitumen　plays　a　vital　role　in　prolonging　the　service　life　of　bituminous　pavement.　A　bituminous　additive　for　resisting　all-weather　ageing　(BARAA),　with　excellent　anti-ageing　performance　and　fewer　side　effects,　was　developed　in　this　study.　The　service　life　of　bitumen　can　be　doubled　by　using　BARAA.　The　results　show　that　the　anti-ageing　index　and　influence　index　can　quantitatively　evaluate　the　anti-ageing　performance　of　anti-ageing　additives.　The　BARAA　was　composed　of　amine　antioxidant　(1.89%　by　weight　of　base　bitumen),　Ni-containing　antioxidant　(3%)　and　hindered　amine　light　stabilisers　(0.7%).　BARAA　effectively　delayed　the　deterioration　of　bitumen　performance　during　ageing.　The　J　(nr)　reduction　of　BARAA-modified　bitumen　caused　by　ageing　was　17.7%　of　the　base　bitumen.　At　-12　degrees　C　and　-18　degrees　C,　the　S　increase　of　BARAA-modified　bitumen　caused　by　ageing　was　about　35%　of　the　base　bitumen.　The　oxidation　during　ageing　was　inhibited.　The　growth　of　sulphoxide　groups　can　be　curbed　by　BARAA.　After　long-term　ageng,　the　aromatic　ring　increase　of　BARAA-modified　bitumen　was　41.1%　of　the　base　bitumen.　In　addition,　the　increase　of　average　molecular　weight　and　functional　group　index　of　BARAA-modified　bitumen　caused　by　long-term　ageing　was　57%　and　19.1%　of　the　base　bitumen,　respectively.
