Summary

Introduction. The analysis of the methods used at the stage of making design decisions for the reconstruction of highways is carried out.

The problem statement. The high cost of road construction and limited resources determine the rational allocation of them to provide maximum cost-effectiveness. This issue can be resolved within the partial reconstruction of the highway. By means of only reconstruction of sections that reduces the riding quality of road or the number of black spots compared to «complete» highway reconstruction (bringing all road elements in compliance with current regulatory requirements), it is possible to significantly save resources. At that, it is necessary to apply a comprehensive approach when adopting the project of complete or partial reconstruction taking into account the actual traffic conditions on the existing road, a detailed analysis of the causes of road accidents and environmental impact with a mandatory consideration of the future consumer impact of the forecasted work complex implementation on the highway as a whole.

Purpose. The purpose of the work is to study the methods used in Ukraine for justification of the highways reconstruction and for the analysis of their performance.

Materials and methods. Analyzing and research methods used in Ukraine for justification of the highways reconstruction.

Results. The expediency of the methods used in Ukraine for justification of the highways reconstruction is determined. The «weaknesses» of each method are identified.

Conclusions. The methods used in Ukraine include the implementation of a complex of works on reconstruction, bringing the technical and geometric parameters of the highway in accordance with the designated technical category. Herewith the technical parameters of the road which do not meet the regulatory requirements but provide the actual operational properties of the road are not taken into account.
