CRACKING OF CONTINUOUSLY REINFORCED CONCRETE PAVEMENTS AT A YOUNG AGE

Abstract

This article explores the effectiveness of continuously reinforced concrete (CRC) pavements in France, focusing on their potential to control transverse cracking and improve competitiveness through reduced reinforcement costs. The "Limited Cracking, Organization of Shrinkage" project (1992-1996) aimed to address these issues through several key activities: modeling CRCP behavior, developing new tests for concrete-reinforcement bond characterization, and conducting experimental and numerical studies to understand the impact of various factors on crack control. The research findings indicate that appropriate longitudinal reinforcement can effectively manage crack spacing and width, offering a promising alternative to traditional jointed concrete pavements. The study contributes valuable insights into optimizing CRC pavement design and performance, highlighting the importance of understanding steel-concrete bonding mechanisms and the influence of reinforcement characteristics on crack behavior.
