Abstract
The article addresses the reliability and cost-effectiveness of road pavements during their design, construction, and operation. The relevance of the study is due to the need to optimize the balance between reliability and economy under resource constraints and quality requirements for roads.
Purpose: The aim of this work is to develop a design approach for flexible pavements that ensures a specified level of reliability with minimum costs.
Methodology: The probabilistic method takes into account a random nature of the pavement strength coefficient and its influence on operational characteristics, including travel speed.
Research findings: A relationship is established between pavement evenness, structural strength, and resulting travel speed. A mathematical model is proposed to determine the best pavement parameters based on minimizing life-cycle costs while maintaining the required level of reliability.
Practical implications: The obtained results prove the selected design solutions considering both operational performance and economic efficiency.
Value: The importance of integrating reliability assessment and cost analysis is emphasized for all stages of the road life cycle to improve the overall efficiency of the road construction and maintenance.
