October 2020: A new paper published at International Journal of Fatigue

  • Crack initiation in bitumen was defined based on fatigue cracking mechanism

  • An energy-based criterion was developed to predict fatigue crack initiation

  • Crack initiation is dependent of modulus, surface energy, crack size and load amplitude

  • Crack initiation criterion was validated and used to determine material surface energy

  • Polymer modification can improve bitumen resistance to fatigue crack initiation

October 2020: A new paper published at Transportation Research Record

  • The crack length in the TS test is determined using a damage mechanics-based DSR-C model

  • The crack evolution is modeled by a pseudo J-integral based Paris’ law

  • Pseudo J-integral Paris’ law is able to predict accurately the crack propagation in bituminous binders

  • The Paris’ law model parameters (A and n) are independent of loading frequency or load amplitude
