Fracture bi-linear model parameters and brittleness of high-performance concretes for paving: why fatigue tests matters and cannot be spared?

ABSTRACT: Fracture tests on two high-performance concrete for pavements were performed using the wedge-split test. The results allowed perceiving same specific fracture energy both concrete. However, crack opening during as well characteristic length of materials resulted in roundly distinct behaviors terms brittleness. Previous fatigue studies concretes are then fairly readdressed pointing out unavoidable needs studying brittleness a parametric way selecting suitable proportions and to reach its microstructural behavior order acquire an appropriate judgment about performance.
