ABSTRACT: This report was prepared as part of an ongoing research effort by the Transportation Systems Center in support of the Urban Mass Transportation Administration of the U.S. Department of Transportation to investigate improved track support systems. The report presents work conducted to evaluate the technical and economic feasibility of using concrete slab track systems for at-grade rapid transit track. This report presents a world-wide review of details and performance of slab track projects. Also, it compares features of slab track systems with those of conventional ballasted track. Methods of constructing slab track systems are also discussed. In addition, a cost comparison between slab and ballasted track systems is presented. Finally, recommendations for future research efforts related to the development of at-grade concrete slab track systems are presented.
