Аннотация
Рассматривается актуальная проблема совершенствования метода неразрушающего контроля состояния нежестких дорожных одежд. В дополнение к разработанному ранее подходу к определению механических параметров материалов конструктивных слоев нежестких дорожных одежд на основе решения обратной коэффициентной задачи о восстановлении эксплуатационных модулей упругости, обеспечивающих заданные поля смещений, был разработан подход, позволяющий определять параметры рассеяния энергии в структуре многослойной дорожной одежды на основе корректировки динамических петель гистерезиса, регистрируемых в полевых условиях и рассчитываемых с использованием математической модели динамического НДС. Приведены результаты численного моделирования динамических петель гистерезиса для двух различных вариантов многослойных конструкций. Показаны возможности корректировки формы петель гистерезиса и их площади путем варьирования тангенсов углов потерь энергии в слоях многослойной среды и модуля упругости однородного полупространства.Комплексная корректировка значений модулей упругости конструктивных слоев дорожных одежд и расчетных петель динамического гистерезиса позволила полностью учесть процессы затухания энергии на удалении от точки приложения нагрузки. В ходе корректировки было установлено, что значения модулей упругости слоев дорожной одежды и тангенсов углов потерь в них оказывают комплексное влияние на площади динамических петель гистерезиса и характера затухания энергии на удалении от точки приложения нагрузки. При этом в наибольшей степени на площадь динамических петель гистерезиса влияние оказывает модуль упругости подстилающего полупространства, не ограниченного по толщине (что привело к увеличению модуля упругости подстилающего полупространства со 120 и 150 МПа для вариантов дорожной конструкции с укрепленным и неукрепленным основанием до 170 и 160 МПа соответственно), а уменьшение рассеиваемой энергии на удалении от точки приложения нагрузки связано, в первую очередь, с тангенсом угла потерь энергии в полупространстве. Полученные значения тангенсов углов потерь, очевидно, связаны с закономерностями рассеяния энергии на границах контактирующих слоев дорожной одежды, а также учитывают все возможные аномалии и расслоения в рассчитываемых конструкциях В рамках данной статьи впервые получены расчетные петли гистерезиса на поверхности дорожной одежды, рассчитана энергия деформирования, исходя из их площадей, и доказана возможность их сопоставления с зарегистрированными экспериментально.

Improvement of the non-destructive method for determining the mechanical characteristics of elements of multilayer structures on the example of pavements
The article is devoted to solving the urgent problem of improving the method of non-destructive testing of the condition of non-rigid road clothes. In addition to the previously developed approach to determining the mechanical parameters of materials of structural layers of non-rigid road coverings based on solving the inverse coefficient problem of restoring operational elastic modules providing specified displacement fields, an approach was developed that allows determining the parameters of energy dissipation in the structure of multilayer road pavement based on the correction of dynamic hysteresis loops recorded in the field and calculated using mathematical model of dynamic VAT. The article presents the results of numerical simulation of dynamic hysteresis loops for two different variants of multilayer structures. The possibilities of correcting the shape of hysteresis loops and their area by varying the tangents of the energy loss angles in layers of a multilayer medium and the elastic modulus of a homogeneous half-space are shown. The complex correction of the elastic modulus values of the structural layers of road clothes and the calculated loops of dynamic hysteresis made it possible to fully take into account the processes of energy attenuation at a distance from the point of application of the load. During the correction, it was found that the values of the elastic modulus of the road layers and the tangents of the loss angles in them have a complex effect on the areas of dynamic hysteresis loops and the nature of energy attenuation at a distance from the point of application of the load. At the same time, the elastic modulus of the underlying half-space is not limited in thickness to the greatest extent on the area of dynamic hysteresis loops (which led to an increase in the elastic modulus of the underlying half-space from 120 and 150 MPa for road construction variants with a reinforced and non-reinforced base to 170 and 160 MPa, respectively), and a decrease in the dissipated energy at a distance from the point of application This is primarily due to the tangent of the angle of energy loss in the half-space. The obtained values of the tangents of the loss angles are obviously related to the patterns of energy dissipation at the boundaries of the contacting layers of the pavement, and also take into account all possible anomalies and delaminations in the calculated structures. Within the framework of this article, calculated hysteresis loops on the surface of the pavement were obtained for the first time, the deformation energy was calculated based on their areas, and the possibility of their comparison with those registered experimentally was proved.
