van Akker, Jorn (author)Because of the sustainability transition in the asphalt industry, it is increasingly popular to apply reclaimed asphalt pavement (RAP) instead of new asphalt. Then, less new material is needed and the amount of waste products is reduced. However, there are questions regarding the performance of asphalt mixtures with high RAP percentages,...master thesis 2022

LI, BOWEN (author)SBS modified bitumen is popularly utilized in road construction owing to its outstanding performance and competitive pricing. However, like normal bitumen, SBS modified bitumen will also be aged and causing asphalt pavement distress and the need for maintenance, resulting in a significant amount of wasted modified asphalt. Recycling waste...student report 2022

Ren, S. (author), Liu, X. (author), Erkens, S. (author), Lin, P. (author), Gao, Y. (author)The molecular dynamics (MD) simulation method is proved as an efficient tool to explore the intermolecular interaction between rejuvenators and aged bitumen, but the simple “singlemolecule” model of rejuvenator would bring the inaccuracy to simulation outputs due to a huge difference with its realistic multi-component chrematistic. This study...journal article 2022

Tabakovic, A. (author)The global road network spans 64.3million km and is of huge significance for the social and economic development. The level of investment in road construction and maintenance is high, e.g. EU €44billion/year (2019), China €614.7billion/year (2019) and US €94billion/year (2019). Despite the level of investment, there has been minimal...journal article 2022

Cem Gursoy, Cemil (author), Kraak, D.H.P. (author), Ahmed, Foisal (author), Taouil, M. (author), Jenihhin, Maksim (author), Hamdioui, S. (author)Memory designs require timing margins to compensate for aging and fabrication process variations. With technology downscaling, aging mechanisms became more apparent, and larger margins are considered necessary. This, in return, means a larger area requirement and lower performance for the memory. Bias Temperature Instability (BTI) is one of the...conference paper 2022

Ren, S. (author), Liu, X. (author), Lin, P. (author), Erkens, S. (author), Gao, Y. (author)Molecular dynamics (MD) simulation is an advanced tool to explore the interaction mechanism between aged bitumen and rejuvenators at the nanoscale. However, the general MD molecular structures of rejuvenators led to the lower quantify and inaccuracy of the simulation outputs. This study aims at developing more realistic molecular models to...journal article 2022

(author)Rejuvenator encapsulation technique showed great potential for extrinsic asphalt pavement damage healing. Once the capsules are embedded within asphalt pavement, the healing is activated on-demand via progressing microcrack. When the microcrack encounters the capsule, the fracture energy at the tip opens the capsule and releases the...journal article 2021
