Abstract:

Existing elastic and viscoelastic fracture mechanics theories have been reviewed and modified to develop a theory capable of predicting the formation of reflective cracking in flexible overlays over rigid pavements due to thermal forces. The developed cracking model is based on fundamental material properties (creep compliance, indirect tensile strength, fracture toughness) and does not use an empirical distress function. Models have also been developed to predict the formation of reflective cracking due to load-associated fatigue. To this extent a FEM analysis model was developed to compute the critical tensile strain in the asphalt overlay over the existing joint or crack and this strain has been related to the allowable strain through laboratory fatigue tests. The developed models have been validated with limited field data, but a complete verification was not possible due to the lack of field projects that also have the required input data.
