Abstract. Significant problem of road branch is premature destruction of flexible pavement.The author made a hypothesis that one of causes of destruction of road designs is their vibration loading. Research of such loading is possible only by means of special dynamic oscillatory models. In article the principles and algorithms of modeling of a frequency range of fluctuations of flexible pavementreveal. The mechanism of creation of models of fluctuations of multilayered pavementis shown.
Keywords: model, fluctuations in the spectrum, the pavement, the given area.
Аbstract. It’s derived the expression for the evaluation of decompactive effect of soil due to its winter freezing. The expression is based on the balance of the phases of soil and pore medium. The well-known interconnection of elastic modulus with humidity and density of cohesive soil allowed to install the expected decrease of the elastic modulus during the spring period of thawing of the roadbed. It can promote the increase of accuracy of pavements condition forecasting.
Keywords: a soil elastic modulus, the humidity and density of soils, binder soils, pavement.
Abstract. The paper contains analysis of indirect traffic management system by the example of foreign experience (the USA) in terms of intelligent transport systems. The paper is divided in two parts. In the first part the examples of indirect traffic management systems are considered. The second part is dedicated to indirect traffic management systems technology in terms of road signs’ and variable message signs’ application.
Abstract. The information on modern techniques of an estimation of a condition of rigid aerodrome pavements and various systems of classification of defects of such pavements is submitted. Association of defects on groups of conformity is executed, and also the analysis of the reasons of occurrence of defects is carried out. The lacks peculiar to considered systems are revealed. The new classification system for the first time allocating both obvious, and latent defects of a design is developed, which allows to execute a complex estimation air field (and road) pavements as designs as a whole.
