Thermal Behavior of Concrete: Understanding the Influence of Coefficient of Thermal Expansion of Concrete on Rigid Pavements

Year: 2025

Type: article

Abstract: Concrete’s coefficient of thermal expansion (CTE) is a critical property affecting the durability and performance of rigid pavements. This review paper examines the significance of CTE in pavement design and the factors influencing it, including the type of aggregate, cement composition, age, relative humidity, and curing conditions. Thermal stress due to temperature changes and moisture variation can lead to cracking, spalling, and warping in concrete pavements, impacting their performance. The paper also discusses experimental methods for measuring CTE, alongside recent advances like mechanistic–empirical pavement design and prediction models. Integrating CTE considerations into pavement design enhances the predictive accuracy of pavement performance, particularly in addressing issues like joint movement and cracking. By comprehensive literature review and synthesizing current research, the paper emphasizes the importance of integrating CTE considerations into pavement design for improved durability and performance predictions. The paper emphasizes the importance of integrating CTE considerations into pavement design for improved durability and performance predictions.
