- The paper is devoted to the technical and economic justification of the automobile road construction of low intensity roads. The design choice offered for comparison presents the construction of roadway surfacing in which the role of the broken stone underlayer is carried out by over-compacted fine soil. In the Volgograd region fine loamy soils (sandy soils, clayly soils) occupy a considerable part of the surface. In this respect the technical and economic justification of the construction of automobile roads for agriculture with the use of over consolidated fine soils of such type in the road construction has a significant social and economic importance. The offered technique of technical and economic justification is founded on the calculation of an actual durability of road constructions using the forecasting of lineal evenness change. The technique of forecasting is based on the improvement of a well known linear multi factor model of the international roughness index (IRI) which forecasts changes in dependence of traffic density and initial state of roadway surfacing due to the inclusion of additional factors into the model. It is suggested to use as factors the data about the qualitative content of traffic load, specifically about the level of impact of heavy cargo vehicles, weather and climate effect on the surfacing and on the quality of automobile road maintenance. The experimental data were subjected to multivariate regression analysis in Excel. In compliance with the data of the test of a trial pavement section constructed in the Bykovskiy district of the Volgograd region, the authors calculated the economic efficiency of the automobile road construction of the offered construction type. The conclusion is drawn on the technical and economic expediency of use of the suggested design solution.
