Diagnosis of automobile roads includes inspection, collection and analysis of information on parameters and conditions of structural elements of automobile roads and road-related facilities, on characteristics of traffic flow and, when necessary, other information for identification of a need for repair and maintenance works as well as evaluation and forecast of road conditions.
Instrumental examination of automobile roads is a set of activities for defining transport and exploitation status of automobile roads.
Within execution of diagnosis, at the formation or update stage of the database on transport and exploitation status of automobile roads, instrumental examination works are carried out to define customary properties at the time of examination.
Examination of roads on a regular basis is necessary for identifying if their characteristics meet the requirements.
Execution of works for diagnosis is carried out with mobile road laboratories fitted with the latest technical equipment and devices for road examination.
A wide range of advanced digital equipment is applied which enables to carry out fast and high-quality diagnostics and instrumental examination of automobile roads that allow to collect full information about the condition of a motor road and artificial road structures on it. The most damaged parts are then selected for further full repair works. As a consequence of examination, technical report with all necessary schedules, conclusions and recommendations is produced.
Also Risk Factors of accidents of the part of the road under study are identified and decision is issued on what type of repair works must be undertaken – spot or full as well as what other works must be conducted and their cost.
Diagnostic System is an essential element that ensures road network remained safe on the basis of signals on condition of its structural elements.
Types of diagnostics and assessment of the condition of roads and the content of initial information:
the purpose of diagnostics and assessment of automobile road condition is to obtain full and reliable information on the transport and exploitation of the status of roads, their working order and compliance with actual customary properties, parameters and characteristics of traffic requirements;
Systematic monitoring is a basis for the management of the condition of automobile roads and material resources aimed at reconstruction, repair and keep of road networks;
Overall assessment of the quality and conditions of automobile roads is carried out in accordance with the indicators of customary properties provided with the actual level of maintenance, geometric parameters, technical characteristics, engineering equipment and service;
As a result of diagnostic works and assessment of the condition of roads during the operation, parts of the automobile roads that don’t meet the regulatory requirements for their transport and exploitation status are identified and types and workload of repair works and measures on keep, repair and reconstruction shall be chosen with a purpose to increase their transport and exploitation status to the level required
The results of diagnostics and assessment of road quality are pre-project
materials and information base for the development of projects of reconstruction, full repair, repair and maintenance of roads in use, in accordance with the established procedure.
Based on the diagnostics and assessment of the condition of roads collected information is used in formation and systematic update of data of Information Systems Administration of road assets of the Republic of Kazakhstan.
