Abstract: A tubular reinforcing dowel system includes a plurality of fiber composite hollow, tubular dowel tubes comprising a first material and each including a longitudinally-extending bore. The dowel tube bores are filled with a second material, such as hydraulic cement, to form dowel members. The dowel members are mounted on a basket assembly which includes a pair of horizontal runners and multiple, longitudinally-aligned pairs of stands mounted on the runners. Each stand is connected to a respective dowel member end. A reinforcing method includes the steps of mounting multiple reinforcing dowel members on a basket assembly, placing the basket assembly on a crushed rock base of a roadway and pouring a cement slab on top of the base and encasing the dowel members underneath a transverse construction joint.
