“…The method can also be used to analyse the presence of moisture due to the difference between the relative dielectric permittivity of the water and air [45]. A significant effect of moisture on the dielectric constant of bituminous mixes was observed [40,[58][59][60][61][62].…”

“…Similar line of analysis, applied to the assessment of the pavement base, was focused on the study of water content, providing promising results and showing that the shift and peaks of the spectrum could most likely be and indicator that help in the mapping of spatial soil moisture variability [60,73]. The spectrum is also sensible to clay content in the pavement base, and several studies point to the possibility of using the peaks displacement to detect changes in clay content [74].…”

“…[12]. A single scatterer, such as a landmine, rebar, or pipeline, reflects a hyperbolic signature in a recorded GPR B-scan profile [13], which can be used to locate the buried objects from GPR images [14]. However, even for an experienced practitioner, interpretation of GPR data is extremely time-and labor-consuming due to complex field conditions and huge data volumes.…”

“…Moisture damage is one of the factors that reduce the lifespan of asphalt pavements due to the presence of water in it and, as a result, intensifies other damages such as fatigue, rutting, pothole, and so on in pavements, especially in rainy areas [1][2][3]. In general, the presence of moisture in pavement causes the bitumen membrane to separate from the surface of the aggregate, resulting in a type of failure that engineers call stripping [4,5]. e main and the most serious consequence of stripping is the loss of strength and integrity of the pavement, which by moving the bitumen over the aggregate surface or breaking the bitumen membrane creates a greater tendency in aggregates to absorb water than their tendency to be covered by bitumen [6][7][8].…”
