Predictive modeling of fatigue and rutting parameters for asphalt cement modified with pretreated oil palm clinker using artificial neural network algorithms to enhance pavement performance

Discover Civil Engineering
Currently, the viscoelastic properties of standard asphalt cement cannot sustain the increasing demands resulting from heavier traffic loads, greater stress levels, and changing environmental conditions. Thus, the usage of modifiers is encouraged.

MOTIVATIONS OF CITIZENS AND ENVIRONMENTAL NGOS: Co‐Producing Urban Greenspaces in Beijing

International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 221-239, January 2026.
Abstract The global governance of urban greenspaces increasingly recognizes the importance of citizen and NGO involvement, since top‐down management often fails to address non‐governmental stakeholders’ diverse perceptions, preferences and demands. Research on public service co‐production and environmental stewardship emphasizes the role of internal ...
