• Abstract:
  This research project investigated the performance and damage characteristics of Nebraska roadways at low-temperature ; conditions. To meet the research objective, laboratory tests were incorporated with mechanistic numerical modeling. The ; three most common pavement structures in Nebraska were selected and modeled considering local environmental conditions ; and pavement materials with and without truck loading. Cracking of asphalt overlay was predicted and analyzed by ; conducting finite element simulations incorporated with cohesive zone fracture. Parametric analyses were also conducted by ; varying pavement geometries and material properties, which could lead to helping pavement designers understand the ; mechanical sensitivity of design variables on the overall responses and performance characteristics of pavement structures. ; This better understanding is expected to provide NDOR engineers with more scientific insights into how to select paving ; materials in a more appropriate way and to advance the current structural pavement design practices.
