This study aims to compare the performance of plain cement concrete (PCC) and ultra-high-performance concrete (UHPC) for rigid pavements using finite element analysis (FEA). The analysis focuses on critical factors such as stress distribution, deflection patterns, and the response of both materials to varying loads, temperature fluctuations, and traffic-induced stresses. Pavement thicknesses are varied between 200 mm and 350 mm to assess how each material performs under different conditions. The study evaluates how UHPC’s superior properties such as higher strength and durability make it a promising alternative to PCC for rigid pavements subjected to heavy traffic and harsh environmental conditions. The results aim to demonstrate UHPC’s enhanced load-bearing capacity, reduced deflection compared to PCC. Ultimately, this research explores the potential of UHPC as a sustainable, high-performance material for future rigid pavement designs, offering long-term benefits in terms of structural performance.

摘要

This study aims to compare the performance of plain cement concrete (PCC) and ultra-high-performance concrete (UHPC) for rigid pavements using finite element analysis (FEA). The analysis focuses on critical factors such as stress distribution, deflection patterns, and the response of both materials to varying loads, temperature fluctuations, and traffic-induced stresses. Pavement thicknesses are varied between 200 mm and 350 mm to assess how each material performs under different conditions. The study evaluates how UHPC’s superior properties such as higher strength and durability make it a promising alternative to PCC for rigid pavements subjected to heavy traffic and harsh environmental conditions. The results aim to demonstrate UHPC’s enhanced load-bearing capacity, reduced deflection compared to PCC. Ultimately, this research explores the potential of UHPC as a sustainable, high-performance material for future rigid pavement designs, offering long-term benefits in terms of structural performance.
