Stress concentration factor as a performance indicator for asphalt mixes

Stress concentration factor as a performance indicator for asphalt mixes Wang, Linbing Primary Author mixed material bibliography ASCE 2007 id Indonesia 16 Ref. ; pp 1-13. Analysis Of Asphalt Pavement Materials And Systems; Emerging Method This paper present some recent developments in using Finite Element Method (FEM) and the 3D microstructure of asphalt concrete reconstructed from x-ray tomography imaging to evaluete its performance. Asphalt concrete is modeled as a material composed of an effective solid and void. The stress concentration factor and its distribution are computed and correlated to the overall resistence of the mixtures agains rutting and fatigue, and the internal structural quantities. The corellation of the stress concentration factor with the field performance of the WesTrack mixed indicates that mixes with large stress concentration factors, as expected, may be more prone to rutting and fatigue cracking than those with smaller stress concentration factors ASPHALT MIXTURE 625.7(063) Perpustakaan Direktorat Bina Teknik Jalan dan Jembatan Direktorat Jenderal Bina Marga - Kementerian Pekerjaan Umum (NPP: 3273244A00000001) 625.7(063) Wan s 0000019147 My Library 625.7(063) Wan s 18476 machine generated
