DESIGN AND CALCULATION OF HIGHWAYS RIGID PAVEMENTS WITH THE USE OF DISPERSED REINFORCEMENT

Abstract

The article presents an analysis of the fiber use for the production of dispersed reinforced concrete. Considerable attention is paid to the use of dispersed reinforced concrete in the construction of road surfaces. Works on the beginning of the 20th century are devoted to the study of dispersed reinforced concrete. One of the promising ways to increase the strength of concrete is disperse reinforcement. Today, to increase the strength there is a need for the use of quality aggregates, highly active cements, low water-cement ratios, as well as dispersed reinforcement with fiber.

The purpose of the design is to select the layers of the structure and their thicknesses in order to make the best use of the mechanical and thermophysical properties of the materials and to ensure the strength, stability, manufacturability and cost-effectiveness of the pavement structure. The method of calculation of rigid type of fiber-reinforced coating is not improved in the article. The calculation takes into account the average daily intensity, the calculated values ​​of bending moments and the standard load on the wheel of the calculation car.
