“…For the density prediction of asphalt concrete layer, the four prediction models chosen from literature-the Birefringence, Boettcher, Linearity indicator, and Rayleigh models-are presented in Equations ( 7)- (10), respectively, which can calculate the bulk density of the asphalt concrete layer using the dielectric constant [20][21][22][23][24].…”

Obtaining the required homogeneity, including uniform thickness and density, is very crucial for controlling the quality of flexible asphalt layers. Although non-destructive testing (NDT) methods are time-saving and less labor-intensive, they only provide indirect measurement data under testing area conditions and strongly depend on the explanations by prediction models. In this study, in terms of the three-dimensional air-launched Ground Penetrating Radar (GPR) technique, the dielectric constant of asphalt concrete base with dry conditions in pavements was detected and calculated by different methods (the Coring Method, Reflection Amplitudes Method and Common Mid-Point Method). According to the calculated dielectric constant, the thickness and density of asphalt concrete base were further calculated and assessed. Comparing with the Coring Method, the Common Mid-Point Method was recommended to calculate dielectric constants in order to obtain reliable thickness of asphalt pavement base. Among the Birefringence, Boettcher, Linearity indicator, and Rayleigh models, the Rayleigh model was suggested to predict the density, and the predicted density exhibited a good correlation coefficient with the measured one. Furthermore, by choosing these proper calculation methods, an assessment was successfully conducted to evaluate homogeneity of a constructed field pavement in practice.

“…Previous studies thus showed that GPR can be used to assess the thickness and density of asphalt concrete layers [20][21][22][23][24][25]. The information from the GPR should be explained and then used to calculate and predict dielectric constant, thickness, and density by using prediction models.…”

В работе представлены результаты экспериментов по использованию сверхширокополосных РЛС подповерхностного зондирования (СШП РЛСПЗ) с трехантенными модулями для систем неразрушающего контроля. Использованные модули имеют различные значения центральных частот зондирующих СШП импульсов и различные конфигурации антенн. Цель проведенных экспериментов заключалась в отыскании наилучших значений параметров чувствительности. Другая задача состояла в оптимизации метода обработки сигналов, отраженных от плоскослоистых сред. Проведенный анализ полученных результатов показал пути улучшения качества неразрушающего контроля дорожного покрытия и других строительных структур при помощи СШП РЛСПЗ. Предлагаемый подход основан на ранее предложенном алгоритме поэтапного определения толщины слоев дорожного покрытия и использовании относительной диэлектрической проницаемости.
