The application of rollable and scalable asphalt mixture structure in Xiaoxichong large-slope bend steel bridge is studied for the first time, car-pet asphalt mixture innovates the pavement structure of steel bridge surface. Mixture has the composite properties of high fatigue resistance, repeated bending strain resistance, high anti-high temperature deformation and anti-low temperature cracking. The study on indoor mixture theory and pavement techniques can provide some theoretical and practical basis for future special steel deck design.%可卷曲和延展性沥青混合料结构在安徽小西冲大坡度弯道钢桥的首次应用研究，地毯式沥青混合料创新了钢桥面的铺筑结构类型。混合料具有较高的耐疲劳性、反复弯曲应变性、抗高温变形和抗低温抗裂的复合性能。通过室内混合料的理论行为研究与现场铺筑工艺行为特征的演变过程，对今后特殊钢桥面的设计结构类型奠定了理论与实践基础。
