钢桥面注浆式OGFC混合料铺装层剪切性能研究

STUDY ON SHEAR PROPERTIES OF GROUTING OGFC FOR STEEL BRIDGE DECK

以注浆式OGFC混合料为钢桥面铺装层,以改善传统钢桥面沥青混合料铺装层易出现推移、拥包、剥离等问题。并通过对钢桥面注浆式OGFC混合料铺装层进行层间抗剪性能和界面抗剪性能测试,研究了钢桥面注浆式OGFC混合料的剪切性能。试验结果表明,注浆式OGFC混合料具有良好的稳定性,且与传统的沥青混合料铺装材料相比,具有较好的层间抗剪性能和界面抗剪性能,可以满足钢桥面的使用。

The grouting OGFC mixture is proposed as the steel bridge deck paving layer,so as to improve the issues that the traditional steel bridge deck asphalt mixture paving layer is prone to slip,encapsulation and stripping.And the interfacial shear performance of grouting OGFC mixture was studied by testing the interlayer shear resistance and interfacial shear performance of the steel bridge deck grouting OGFC mixture pavement.The test results indicated that the grouting OGFC mixture has good temperature stability,and compared with the traditional asphalt mixture pavement material,it has better interlayer shear performance and interface shear performance.Therefore,the grouting OGFC mixture can meet the requirements of steel bridge decks.
