Diagnosis and Recognition of Pavement Structural Defects Based on Acoustic Emission Principle

Abstract:

Through extensive literature research, this paper from the principle of acoustic emission technology, development and application of acoustic emission technology at home and abroad, the characteristics of acoustic emission technology, acoustic emission instrument classification, structure and technical indicators of acoustic emission technique is applied to the aspects of pavement structure defect diagnosis about the prospect of the system in this paper. Introducing the SAEU2S acoustic emission system structure and technical indicators of acoustic emission instrument applied in pavement structure for the future defect diagnosis recognition provides the reference. Research results objectively show the non-destructive testing technology for pavement maintenance performance detection technology advantage, basic principle and method of then for pavement dynamic maintenance tracking and evaluation of real-time traffic all the way, maintenance decision information and the realization of the institutionalization of laid a foundation.
