Abstract. A summary of literature on performance testing of Full Depth Reclamation (FDR, also known as Bitumen Stabilization) is presented in this paper. FDR is an important pavement rehabilitation treatment that can eliminate severe distresses and improve pavement structure, while using environmentally friendly techniques. FDR can be considered a semi-bound material (when stabilized with asphalt emulsion or asphalt foam) or a semi-rigid material (when stabilized with cementitious material). Performance testing of FDR has roughly followed that of traditional asphalt mixtures over the past forty years, with a time lag of approximately ten years, and has also incorporated several test from soil mechanics. Water in the FDR, cur-ing time, curing state, curing temperature, and final testing conditions are of upmost importance, and there are not a consistent guidelines for these. In addition, the three stabilization methods of FDR behave very different, and existing asphalt mixture or soils tests may need to be modified to test FDR.
