Numerical simulation of asphalt mixture based on three-dimensional heterogeneous specimen
Abstract：In order to verify the validity of finite element numerical simulation method for asphalt mixture,which consists of aggregates,mastic (where mastic is a kind of fine mixture composed of asphalt binder mixed with fines and fine aggregates) and air voids,based on three-dimensional (3D) heterogeneous specimen,X-ray computerized tomography (X-ray CT) was used to scan the asphalt specimens to obtain the real internal microstructures of asphalt mixture.CT images were reconstructed to build up 3D digital specimen,and the viscoelastic properties of mastic were described with Burgers model.The uniaxial creep numerical simulations of three different levels of aggregate gradation were conducted.The simulation results agree well with the experimental results.The numerical simulation of asphalt mixture incorporated with real 3D microstructure based on finite element method is a promising application to conduct research of asphalt concrete.Additionally,this method can increase the mechanistic understanding of global viscoelastic properties of asphalt mixtures by linking the real 3D microstructure. 作者： Author： ZHANG Xiao-ning[1] WAN Cheng[1] WANG Dong[2] HE Ling-feng[1] 作者单位： Department of Civil and Transportation Engineering, South China University of Technology,Guangzhou 510640, ChinaDepartment of Civil and Environmental Engineering, Virginia Polytechnic Institute and State University,Blacksburg 24060, USA 期 刊： 中南大学学报（英文版） EISCI Journal： Journal of Central South University of Technology(English Edition) 年，卷(期)： 2011, 18(6) 分类号： U416.217 Keywords： asphalt mixture X-ray CT 3D heterogeneous specimen numerical simulation 机标分类号： TB3 O6 机标关键词： based viscoelastic properties asphalt mixtures numerical simulations microstructure finite element method computerized tomography simulation results fine aggregates asphalt binder understanding application X-ray three different air voids research levels order scan 基金项目： supported by the National Natural Science Foundation of China Numerical simulation of asphalt mixture based on three-dimensional heterogeneous specimen[期刊论文] 中南大学学报（英文版） --2011, 18(6)In order to verify the validity of finite element numerical simulation method for asphalt mixture,which consists of aggregates,mastic (where mastic is a kind of fine mixture composed of asphalt binder ...【Numerical simulation of asphalt mixt】相关文章：
