Thermal reflective cracking of asphalt concrete overlays
International Journal of Pavement Engineering, 2010Reflective cracking of asphalt concrete (AC) overlays is one of the most extensive pavement distress and damage mechanisms in composite pavement structures. Numerous studies have been performed to evaluate the reflective cracking potential of AC overlays under different loading scenarios. Most of these studies have focused on reflective cracking due to

The reflective cracking phenomenon occurs when joints and cracks in a pavement that is generally made of concrete or cement-treated layers propagate up through the asphalt overlay and appear on the pavement surface. These cracks allow water to enter and cause the pavement deterioration process to accelerate, thereby increasing maintenance costs.

Cohesive Cracking Simulation of Asphalt Mixture with Reflective Crack through XFEM
Applied Mechanics and Materials, 2012Firstly, the parameters of cohesive zone model in ABAQUS software are calibrated through the cohesive constitutive model determined by cohesive potential energy, which is provided by Oriz and Pandofi（1999）. Then, the validity and liability are verified by the single element example which compares extended finite element simulation with experimental ...

Mechanistic-Empirical Approach for Modeling Reflection Cracking
Transportation Research Record: Journal of the Transportation Research Board, 2000Models developed to predict reflective cracking in flexible pavement overlays do not explicitly incorporate the combined effect of the cracked and uncracked areas in the original pavement. This affects the development of cracks in the overlay. Therefore, a model is needed that will incorporate this factor explicitly, making predicting of cracking in ...
