Sustainable　and　resilient　pavement　infrastructure　is　critical　for　current　economic　and　environmental　challenges.　In　the　past　10　years,　the　pavement　infrastructure　strongly　supports　the　rapid　development　of　the　global　social　economy.　New　theories,　new　methods,　new　technologies　and　new　materials　related　to　pavement　engineering　are　emerging.　Deterioration　of　pavement　infrastructure　is　a　typical　multi-physics　problem.　Because　of　actual　coupled　behaviors　of　traffic　and　environmental　conditions,　predictions　of　pavement　service　life　become　more　and　more　complicated　and　require　a　deep　knowledge　of　pavement　material　analysis.　In　order　to　summarize　the　current　and　determine　the　future　research　of　pavement　engineering,　Journal　of　Traffic　and　Transportation　Engineering　(English　Edition)　has　launched　a　review　paper　on　the　topic　of　＂New　innovations　in　pavement　materials　and　engineering:　A　review　on　pavement　engineering　research　2021＂.　Based　on　the　joint-effort　of　43　scholars　from　24　well-known　universities　in　highway　engineering,　this　review　paper　systematically　analyzes　the　research　status　and　future　development　direction　of　5　major　fields　of　pavement　engineering　in　the　world.　The　content　includes　asphalt　binder　performance　and　modeling,　mixture　performance　and　modeling　of　pavement　materials,　multi-scale　mechanics,　green　and　sustainable　pavement,　and　intelligent　pavement.　Overall,　this　review　paper　is　able　to　provide　references　and　insights　for　researchers　and　engineers　in　the　field　of　pavement　engineering.　(C)　2021　Periodical　Offices　of　Chang＇an　University.　Publishing　services　by　Elsevier　B.V.　on　behalf　of　KeAi　Communications　Co.　Ltd.
