Assessing the environmental aging behaviour of antioxidant modified bitumen via chemo-mechanical analysis

Antioxidants can mitigate bitumen aging, improving asphalt durability. This study evaluates the aging prevention performance of zinc diethyldithiocarbamate (ZDC). Three laboratory aging methods (extensive thermal (3xPAV), thermo-chemical, and photo-thermal aging) were compared wi...

Influence of Modeling Assumptions on the Structural Performance of Flexible Airfield Pavements Using FAARFIELD and Demoiselle

Abstract The design of airfield pavements is commonly performed using mechanistic–empirical methods implemented in software tools. Although consolidated, these tools incorporate simplified modeling assumptions that may influence the estimated structural responses. In this context...
