Abstract

One of the most important decisions made in using full depth reclamation (FDR) as a rehabilitation technique is the choice of stabilization agents. Amongst the numerous ways of improving the properties of rehabilitating deteriorated pavements is FDR stabilized with media like Portland cement, emulsified asphalt, foamed asphalt, lime, fly ash. However, the subject of choosing the right stabilizing medium for FDR rehabilitation remains one governed by empirical understanding of the rehabilitation process. This paper research FDR practices and aims to develop a suitable guide for selecting appropriate FDR stabilizing agents, based on the structural properties, material properties, environmental properties and climatic properties of the pavement and its location. The research in this paper uses a factorial method to analyze the performance of pavement models across the United States generated using the AASHTO MEPDG program (AASHTOWare), and it compares the structural performance from case studies cement and asphalt stabilized FDR in the state of Tennessee.
