摘要

The urgency of deploying automated weighting and dimension control stations on highways is explained due to the significant growth of freight traffic using road transport. The study substantiates the critical issue of pavement wheel tracking within weighing and dimension control stations. Addressing this problem is essential because road surface conditions at measurement points significantly influence the accuracy of controlled parameters. To minimize errors in dynamic vehicle weighing, maintaining specified pavement smoothness standards must be prioritized. The article analyzes the operating control stations in the Republic of Bashkortostan and Krasnodor Territory. The adopted structure of road pavements in various sections, both with rigid and non-rigid pavements, is described herein. The results of computational analysis of wheel tracking depending on the ambient temperature effect for different types of pavements are given. Findings indicate that elevated temperatures cause softening of the organic binder leading to reduced strength characteristics in asphalt concrete layers, thereby consequently accelerating plastic deformations contributing to rapid wheel tracking formation. These deficiencies are absent in cement concrete pavements. The study also examines the influence of base stiffness in both rigid and non-rigid pavement structures. The results demonstrate that a low elastic modulus of the base layer significantly increases residual vertical deformations, particularly within wheel load zones, thereby requiring for base reinforcement during engineering, especially under heavy traffic conditions and frequent heavy vehicles. This effect is observed across all pavement types, though concrete pavements exhibit reduced susceptibility due to their superior load-distribution capacity.
