Numerical Analysis of Reflective Cracking in an Asphalt ...

2014-7-21  This paper investigates the reflective cracking mechanism in an AC overlay over flexible pavements under different loading conditions by using a finite element (FE) analysis with bonded and unbonded conditions. The FE simulations also include partial top-down cracking conditions in the underlying flexible pavement.

Theoretical Analysis of Reflective Cracking in Asphalt ...

2018-9-18  Reflective cracking in semi-rigid base asphalt pavement is one of the major pavement diseases, and the main purpose of this study is to explore the cause of the reflective cracking. In order to simplify the problem, an asphalt concrete pavement containing a crack in semi-rigid base was modelled as elastic multilayer. Based on the linear-elastic superposition principle, the model was decomposed ...

2020-4-14  2. Numerical Analysis. The mechanism of reflective cracking formation can be summarized as follows: owing to the original defects in the joints and cracks of the old airfield cement concrete pavement, and the stress generated from the pavement structure is discontinuous at the defects under temperature cycle variation and traffic load, leading to the larger stress concentration phenomenon.
