ABSTRACT
Feasibility of in-service maintenance measures should be validated not only by visual inspection of pavement but also by the results of laboratory testing of materials of monolithic pavement layers and by evaluation of defects and deterioration degree using non-destructive thermal imaging inspection methods. The paper presents thermal imaging inspection results (Infrared Thermal Imaging) of the following basic defects of pavement: chipped corners of slabs at the edge of pavement; reflected cracks; local deterioration followed by scaling; longitudinal cracks; net of cracks; deformation of joints. Basing on the inspection results, bar charts of concrete strength distribution within the pavement as well as temperature fields per individual defective area were compiled. Dependences for calculating the degradation degree of the material of pavement structure and for the design of pavement reinforcement in terms of “durability-cost” are presented. The paper can be used for the purposes of pavement management system implementation.
