Description

The aim of the dissertation is based on the properties of flexible road pavement structures to develop a mathematical models for predicting the performance of wearing courses used in the pavements of the main roads. The main tasks of the dissertation are as follows: to analyze the main factors influencing the service indices of asphalt concrete pavements and to determine their reasons; to investigate the quality of materials and mixtures used in pavement structural layers of the main roads; to determine the interaction between asphalt concrete pavement composition and the quality indices of mixture materials; to study regularities of the change in pavement roughness and rut depth; to determine the interaction between the quality indices of materials used in pavement structural layers; to select two rational flexible pavement structures for the main roads (for the different traffic volume).

The dissertation consists of introduction, four chapters, general conclusions, the list of references and the list of author’s publications on the topic of the dissertation, addenda.

Introduction describes the studied problem, topicality of the problem, the object of research, also the aim and tasks, research methodology, scientific novelty, practical value of the results and the defended propositions.

Chapter 1 gives the analysis of scientific researches made by different countries in the field of the performance of asphalt concrete pavements and their structures, duration of their service life.

Chapter 2 describes theoretical investigations to determine the service indices of asphalt concrete pavements and their structures, material properties of pavement structural layers, and time intervals between pavement repairs.

Chapter 3 gives the research methodology, presents investigations in the service indices of asphalt concrete pavements and material properties of structural pavement layers, as well as their interaction. Also, studies the physical, mechanical and geometrical indices of materials used in pavement structural layers.

Chapter 4 suggests mathematical models for predicting asphalt concrete pavement service indices in a period of 5 years. Two rational flexible pavement structures have been selected for the main roads: for the traffic volume of 10 000 veh./day and up to 30 000 veh./day.

On the topic of the dissertation 6 scientific articles have been published: two – in scientific journals included into the list of Thomson Reuters Web of Knowledge, three – in the reviewed international conference proceedings included into the Thomson ISI Proceedings, one – in the proceedings of international conferences.
