Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The main purpose of the examination of roads is the timely identification of areas that require improvement of road conditions, as well as the evaluation of the state of all structural elements of roads. The study of the causes of road deformations, measures to eliminate and prevent warping are the main issue of road maintenance. The survey of roads was conducted in accordance with the approved methods using standard measuring tools. PLAXIS software was used to perform the finite element analysis of deformations and stability of soil, to calculate the interaction of the pavement with the ground, the effect of heat fluxes. Processing of data on the road Almaty-Taraz has shown that stresses and deformations arise directly in the place of contact of point loads with trapezoidal shape on the depth of influence. The authors conclude that when horizontal deformations occur, the greatest stresses occur on the road shoulders, which surrounds possible slope collapses. In addition, volumetric deformations of the foundation occur under direct dynamic loading and, under its prolonged effect, contribute to the appearance of volumetric bulging deformations.
