ZERO-MAINTENANCE DESIGN FOR PLAIN JOINTED CONCRETE PAVEMENTS

Abstract
This study outlines a design approach for plain jointed concrete pavements intended for heavy traffic, emphasizing a "zero-maintenance" performance over a designated period. The concept of "zero-maintenance" targets the absence of structural maintenance activities such as crack repair and slab replacement. Through extensive field surveys across various regions and comprehensive analytical studies using mechanistic models, researchers developed two distinct structural design approaches. One employs a new serviceability/performance model based on historical data from the original AASHO Road Test and other sources, while the other leverages a mechanistic fatigue analysis model to evaluate the impact of traffic load and environmental factors like thermal curling. The application of these models is supported by a novel computer program, JCP-1, designed to assist engineers in the rigorous design process. The procedures are validated by field data, ensuring their practical applicability for real-world engineering challenges. The study is backed by the Federal Highway Administration, highlighting its significance in advancing pavement engineering to meet modern traffic demands and environmental conditions.
