Abstract
To assess three-dimensional ground-penetrating radar (GPR) applicability for evaluating interlayer bonding in asphalt pavements with semi-rigid base layers, and analysis the GPR detection mechanism. Using forward simulation to create various medium models and analyze electromagnetic wave transmission in air, water, and sand. Four distinct pavement structures were subjected to GPR testing, and the amplitude intensity levels and image processing techniques to assess asphalt pavement interlayer bonding, and validated by comparing the results with core samples. The findings revealed that electromagnetic wave transmission processes were significantly influenced by medium uniformity. Non-uniform medium models generated considerable stray waves, akin to typical "noise," closely mirroring real pavement conditions. Poorly bonded areas exhibited clearer hyperbolic ripples, primarily due to significant differences in dielectric constants of filling materials. Amplitude strength effectively evaluated bonding across different asphalt pavement configurations and lanes, typically following a normal distribution. Enhanced interlayer contact correlated with smaller amplitudes, while weaker bonding led to larger amplitudes. The amplitude distribution in the center of lanes differed significantly from wheel track areas, and the interlayer bonding condition of center lanes was better than wheel track belt. Additionally, radar plan views exhibited considerable variation across different interlayer contact conditions. The image processing method can evaluate the interlayer contact condition of different pavement structures across full cross-sections.
期刊介绍：
Measurement Science and Technology publishes articles on new measurement techniques and associated instrumentation. Papers that describe experiments must represent an advance in measurement science or measurement technique rather than the application of established experimental technique. Bearing in mind the multidisciplinary nature of the journal, authors must provide an introduction to their work that makes clear the novelty, significance, broader relevance of their work in a measurement context and relevance to the readership of Measurement Science and Technology. All submitted articles should contain consideration of the uncertainty, precision and/or accuracy of the measurements presented.
Subject coverage includes the theory, practice and application of measurement in physics, chemistry, engineering and the environmental and life sciences from inception to commercial exploitation. Publications in the journal should emphasize the novelty of reported methods, characterize them and demonstrate their performance using examples or applications.
