GEORADAR DIAGNOSTICS OF ROAD PAVEMENT CONDITION

The monograph presents the theoretical foundations, methods, and practical approaches to processing ground-penetrating radar (GPR) survey data for solving the problem of defectoscopy in flexible pavement, considered as a plane-layered structurally heterogeneous medium, and for further evaluation of its condition.The methods for assessing the structural reliability and risk of failure of flexible pavement based on GPR diagnostics involve incorporating GPR survey results into the calculations of the stress-strain state of the structure while accounting for its structural heterogeneity. This heterogeneity is associated with localized material discontinuities, statistical and probabilistic methods, and risk theory, allowing for the determination of structural reliability considering variations in geometric and physico-mechanical parameters.The practical defectoscopy methodology addresses the task of positioning subsurface cracks within the structure. The reliability and failure risk assessment methodology substantiates the parameters of the computational model and regulates the calculation procedures for structures with subsurface heterogeneities.
