摘要
大孔隙沥青混合料(PAM)具有优良的排水、抗滑、降噪等功能,符合现代节能环保、以人为本的新设计理念。研究采用数字图像处理技术(DIP),通过图像边缘检测、图像二值化、几何矢量化得到了大孔隙沥青混合料具有几何交换格式的图像,在此基础上,采用有限元仿真技术建立了大孔隙沥青混合料的有限元模型,分析了劈裂试验下混合料内部的应力应变响应,研究成果表明该方法可进一步应用于不同条件下大孔隙沥青混合料细观力学响应模型研究。
The porous asphalt mixture（PAM）,with excellent drainage,skid,noise reduction and other functions,conforms with the design philosophy of modern energy saving,environmental protection and people-centered.In this study,the digital image processing（DIP） is used to get the geometry interchange format of the PAM,through image edge detection,image binarization and geometric vector image.Then using the finite element simulation technology,the PAM＇s finite element model is build.And the stress-strain response of the internal mix is analysed by the split test.The results show that,the method can be further applied to the microscopic structure response of PAM model under different conditions.
