Title: A Distributed Simulation Framework Using HLA for Circular Economy Modeling in Road Construction Authors: Tim Bernhard, Omar Abbasi, Joseph Louis, Johannes Fottner Abstract: Road construction consumes large quantities of virgin aggregates and asphalt, while circular-economy (CE) strategies, such as using reclaimed asphalt pavement (RAP) and recycled aggregates, remain underutilized due to quality uncertainties, logistical constraints, and limited digital integration. Existing simulation tools are predominantly linear and single-site, which prevents the realistic evaluation of ...
