摘　　要：沥青混凝土路面坑槽多采用热拌沥青混合料的修补方法,养护受季节影响较大。若坑槽修补不及时,就会导致路面结构大面积破坏、路基翻浆等病害。冷补材料可以在较低的温度下施工,坑槽修补不受季节限制,其强度形成机理、拌合方式、施工方法、储存方法与热拌沥青混合料均不同。文中选择合适的冷补材料组成,分析冷补材料强度形成机理,并对初始强度和成型强度试验结果进行分析。The asphalt concrete pavement pit slots are mostly patched by heating asphalt mixtures,and pavement maintenance is more obviously influenced by the seasonal change.If the pit slots are not repaired in time,it will cause many highway diseases,for instance,the pavement structure large area destroyed and subgrade mudding.Cold patching asphalt mixtures construction may be used at lower temperature and the pot holes patching are not restricted by seasons,and is different from heating asphalt mixtures about mechanism of strength,mixing mode,construction and storage method.This paper has investigated how to choose appropriate composition of cold patching asphalt mixtures,and analyzed mechanism of strength and test results of initial strength and forming strength.
