Full Depth Reclamation: “Rubblizing” Asphalt

This article describes full depth reclamation (FDR) defined by the Asphalt Recycling and Reclaiming Association (ARRA) as a pavement rehabilitation technique in which the full flexible pavement section and a pre-determined portion of the underlying materials are uniformly crushed, pulverized, or blended, resulting in a stabilized base course. The author reviews candidate pavements, the primary steps in FDR, analyzing the field samples to develop an effective FDR mix design, pulverizing the pavement, introducing additive and mixing, asphalt stabilization, mechanical stabilization, chemical stabilization, shaping and compacting, and final surfacing. One case study is used to illustrate the concepts discussed – the rehabilitation of Markey Road, in Lebanon, Ohio. The author concludes that FDR offers a positive option for converting a worn-out asphalt pavement into a stabilized base course.
