Pulverization of pavement base materials is routinely carried out for rehabilitation of roadsthrough full-depth reclamation (FDR). The pulverized materials are then, either as-is or mixed with a stabilizer,re-compacted in place. The optimum stabilizer type and content are currently determined either based on expe-rience or through a series of laboratory tests that evaluates the strength, stiffness and durability of the mix. Forlab testing, base materials are retrieved from the site way before pulverization. An extensive laboratory studywas performed to determine the impact of changes in gradation on the performance of bases in order to achievethe desirable performance. It was found that the change in gradation indeed impacts the properties of the mixand the amount of stabilizer needed, and should be considered in the design stages of FDR.
