Abstract: This paper aims to deepen researches on void detection beneath rigid pavements. Detailed investigation and analysis are made with regard to the academic research status, existing problems and development prospect about correlational research both at home and abroad. Firstly, the origin of deflection -based method and the commonly used deflectometer are respectively introduced; Secondly, the deflection-based identification methods are reviewed and the problems and application limitations in existing researches are analyzed in detail; Finally, the key issues and research trend for deflection -based identification of void beneath slab are presented. The difference between the effect of joint load transfer and void beneath rigid pavements on deflection is suggested to be the focus of further researches.

Key words: rigid pavements, void beneath slab, deflection, joint load transfer
