Qian ZHAO, Zhoujing YE

Frontiers of Structural and Civil Engineering 2018, Volume 12, Issue 2,   Pages 201-206 doi: 10.1007/s11709-017-0402-1

Abstract: Fracture and fatigue cracking in asphalt binder are two of most serious problems for pavement engineersconsists both of dimensional analysis using Buckingham Theorem and -integral analysis based on classic fracturemechanics, to evaluate the fracture and fatigue on asphalt binder.is discovered that the dimensional analysis could provide a new perspective to analyze the asphalt fractureand fatigue cracking mechanism.
