Road　facilities　are　one　of　the　huge　infrastructures,　which　are　huge　in　size　and　wide　in　distribution,　and　play　an　important　role　in　the　national　economic　development　and　the　daily　lives　of　the　people.　In　the　process　of　construction,　operation,　maintenance　and　demolition　of　road　infrastructure,　not　only　are　a　large　number　of　new　building　materials　needed,　but　also　a　lot　of　waste　materials　are　produced.　In　this　process,　a　large　amount　of　energy　is　needed　for　the　production　and　transportation　of　building　materials　and　the　operation　of　various　construction　equipment　during　construction.　At　the　same　time,　a　large　amount　of　CO2　and　other　harmful　gases　are　generated.　Therefore,　the　research　and　application　of　energy-saving　and　emission-reduction　technologies　in　the　field　of　road　infrastructure　are　of　great　significance　for　achieving　the　dual　carbon　target.　First,　the　carbon　emission　problems　existing　in　China＇s　road　infrastructure　construction　were　introduced.　Second,　the　characteristics　and　application　of　energy-saving　and　emission-reduction　technologies　of　more　mature　road　infrastructure　construction　at　domestic　and　overseas　were　introduced.　Third,　the　development　direction　and　trend　of　future　energy　saving　and　emission　reduction　technologies　were　analyzed.　The　analysis　shows　that　new　technologies　in　road　infrastructure　construction　and　operation　management　can　play　an　important　role　in　energy　conservation　and　emission　reduction.　The　research　and　development　of　innovative　technologies　and　the　promotion　and　application　of　mature　technologies　should　be　strengthened　in　the　future.　©　2022,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
