The dissertation was defended at the public meeting of the Dissertation Defence Council of Civil Engineering in the Aula Doctoralis Meeting Hall of Vilnius Gediminas Technical University at 10 a.m. on 14 May 2025.
The dissertation examines the stresses, deformations, and fatigue of roller-compacted concrete pavement structures installed on the base of soils bounded with hydraulic binders. The dissertation aims to investigate the fatigue function parameters of roller-compacted concrete pavements installed on a base layer of soils bound with hydraulic binders and other additives and to develop rational solutions and technical specifications for roller-compacted concrete pavement structures. The dissertation consists of an introduction, three chapters, general conclusions and recommendations, references, and a list of scientific publications by the author on the topic of the dissertation, as well as a summary in English. The introduction discusses the research problem and the relevance of the dissertation, describes the research objects, and formulates the purpose and tasks of the dissertation, scientific novelty, the practical significance of the dissertation results, defensive statements, and the research methodology. The first chapter of the dissertation presents a literature analysis on the performance of roller-compacted concrete pavement structures, calculation methods and fatigue functions applied in their algorithms, and variables of fatigue functions. At the end of the chapter, the main objectives of the dissertation are formulated. The second chapter analyses the influence of hydrothermal effects on the structure of the roller-compacted concrete pavement and determines the actual stresses at the bottom of the roller-compacted concrete layer. It also analyses the joint load transfer and base erosion models. The third chapter presents the computational scheme of pavement structure, which is based on the actual mechanical properties of the pavement structure, determined by the experimental studies and the control of the installation of the pavement structure layers during the reconstruction. Also, it provides recommended variants of pavement structures based on the computational scheme. The third chapter also provides requirements for pavement structure layers and controls for installing pavement structure layers. Three scientific articles were published on the topic of the dissertation in scientific journals included in the Web of Science database. The results of the research conducted in the dissertation were presented at three international conferences.
