Abstract

A desire to maintain a safe, efficient, and cost-effective roadway system has led to a significant increase in the demand to rehabilitate the existing pavements. Asphalt pavement recycling has grown dramatically over the last few years as the preferred way to rehabilitate existing asphalt pavements. Full-depth reclamation with foamed asphalt (FDR-foam) has been employed in the rehabilitation of existing asphalt pavements in many countries. The objective of the case study is to determine the optimum foaming water content needed to produce the best foam properties for a given asphalt binder and the optimum foamed asphalt content to produce the best FDR-foam mixture. Based on the limited laboratory test results, the optimum foaming water content of 1.75% was selected to achieve an expansion ratio of 6.7 and a half-life of 11 seconds and the optimum foamed asphalt content between 2.5% and 3.0% is recommended.
