... bitumen rheology, where higher DOC corresponds to higher resistance to permanent deformation and lower resistance to fatigue damage. However, this study identifies that DOC is not the only parameter that dominates the behavior; the melt flow index (MFI) of polymers also plays a crucial role in defining...

...Zhenfeng He; Jianting Zhou; Dingkun Liu; Leng Liao In light of the intrinsic relationship between weld fatigue damage and the characteristics of magnetic leakage signals, fatigue experiments were conducted on butt welds to analyze the evolution of magnetic leakage signal as fatigue cycles increased...

... increased with increasing specimen sizes and decreased with increasing temperature. SUP-25 had an enormous fatigue damage value (0.419) after 5,400 times repeated loading. The error between the rutting simulation and test results was 2.87 %, indicating that the model effectively applies to multilayer...

... butadiene styrene block copolymer modified asphalt mixture, were conducted using closed-loop test system. The fatigue damage variable was defined by the modulus attenuation based on the theory of damage mechanics, and the modulus attenuation equation was deduced. Under the same conditions, the initial value...

...Quantao Liu; Jin Tang; Liang He Asphalt binder is a self-healing material and it has a potential to heal faster with increased temperatures. This paper investigates the thermally activated healing of fatigue damage in three asphalt binders, trying to answer the question: At what temperatures do...

...S. Joon Lee; Youngguk Seo; Y. Richard Kim Stress wave analysis is employed herein as a nondestructive monitoring tool to assess the level of fatigue damage in a thin asphalt concrete (AC) overlay. A frequency-dependent cross-correlation procedure is developed to specify a stress wave at a desired...
