Gao, Y. (author), Liu, X. (author), Ren, S. (author), Assaf Martinez-Streignard, E.I. (author), Liu, Pengfei (author), Zhang, Yuqing (author)Bitumen fatigue resistance is critical to determine the overall fatigue performance and service life of asphalt pavements. However, the mechanisms responsible for fatigue damage of bitumen have previously not been well understood. Molecular dynamics (MD) simulation has recently emerged as a powerful computer-aided numerical technique to model...journal article 2024

Li, Chenchen (author), Yang, Fan (author), Liu, Pengfei (author), Fu, Chaoliang (author), Liu, Quan (author), Zhao, Hongduo (author), Lin, P. (author)To improve the energy harvesting efficiency of the piezoelectric device, a stack units-based structure was developed and verified. Factors such as stress distribution, load resistance, loads, and loading times influencing the piezoelectric properties were investigated using theoretical analysis and experimental tests. The results show that the...journal article 2021

Lu, Guoyang (author), Wang, H. (author), Zhang, Yuqing (author), Liu, Pengfei (author), Wang, Dawei (author), Oeser, Markus (author), Grabe, Jürgen (author)The pore-water pressure generated by intermittent dynamic vehicle loading under various saturation states is recognized as a critical factor influencing the behaviour of permeable pavement structures, especially the behaviour of UGB layer. However, the underlying mechanisms of hydro-mechanical interaction in the UGB layer and the influence on...journal article 2021

Du, Cong (author), Lu, Guoyang (author), Wang, H. (author), Sun, Yiren (author), Liu, Pengfei (author), Wang, Dawei (author), Leischner, Sabine (author), Oeser, Markus (author)Porous asphalt (PA) pavements are widely employed in areas with wet climates. As particle enhancement inclusions in asphalt mastic, mineral fillers play essential roles in improving the performance of PA pavements. This study developed a coupled multiscale finite element (FE) model, involving the mesostructure of PA mixture and PA pavement....journal article 2021

Liang, Hongqin (author), Liu, Pengfei (author), Wang, Tianlong (author), Wang, Haoyu (author), Zhang, Kailong (author), Cao, Yunqiang (author), An, Dong (author)For a heavy-haul locomotive within a wheel repairing period, wheel polygonal wear with different operating mileages is obtained by field testing. The test results show that the maximum radial runout of the wheel can increase to 0.87 mm and accompany with the typical damage of wheel tread shelling. Taking the wheel polygons as input excitation...journal article 2020

Hu, Zhihui (author), Xu, Tao (author), Liu, Pengfei (author), Oeser, Markus (author), Wang, H. (author)To reduce the thermal-oxidative aging of asphalt and the release amount of harmful volatiles during the construction of asphalt pavement, a new composite anti-aging agent was developed. Since the volatiles were mainly released from saturates and aromatics during the thermal-oxidative aging of asphalt, expanded graphite (EG) was selected as a...journal article 2020
