Abstract:
Continuously reinforced concrete pavement provides the basis for a low cost, low maintenance sup-port structure for automated transit systems where the alignment can be run at-grade. Design criteria, solutions, construction methods, and pavement per-formance are presented for both a rubber tire system and a steel wheel-on-rail system. The continuously welded rails of the latter are directly fixed to the concrete pavement. The Airtrans People Mover at the Dallas/Fort Worth Airport and the Kingston, Ontario, Test Center for the Canadian Intermediate Capacity Transity System are the projects described. Expansive clay soils, extreme thermal gradients, and rail/pavement interaction are some of the design problems encountered. [Authors]
