《温拌沥青混合料配合比设计规程》简介本规程旨在规范温拌沥青混合料（WarmMixAsphalt,WMA）的配合比设计流程，确保其性能满足道路工程的技术要求。温拌沥青混合料是一种环保型材料，通过降低拌合与施工温度（通常比热拌沥青低20-40°C），显著减少能源消耗和温室气体排放，同时保持良好的路用性能。规程内容涵盖原材料选择、级配设计、温拌剂掺量确定、混合料性能验证（如马歇尔稳定度、水稳定性、抗车辙能力等）以及施工工艺控制。适用于各等级公路、城市道路的温拌沥青混合料设计，兼顾技术可行性与环境可持续性。**DesignSpecificationforWarmMixAsphalt(WMA)MixtureProportioning**ThisspecificationstandardizesthemixdesignprocessforWarmMixAsphalt(WMA),ensuringcompliancewithroadengineeringperformancerequirements.WMAisaneco-friendlymaterialthatreducesmixingandpavingtemperatures(typically20-40°ClowerthanHotMixAsphalt),significantlycuttingenergyconsumptionandgreenhousegasemissionswhilemaintainingpavementperformance.Theguidelinesincluderawmaterialselection,gradationdesign,WMAadditivedosage,performancevalidation(e.g.,Marshallstability,moistureresistance,ruttingresistance),andconstructioncontrols.Applicabletohighwaysandurbanroads,itbalancestechnicalfeasibilitywithenvironmentalsustainability.
