ABSTRACT:
A roadbed and a curb are formed as a single integral structure by slip-forming concrete material using a tracked vehicle supporting a roadbed slip-form and a curb slip-form which extend along opposite sides of a track of the vehicle so leaving a gap between the formed roadbed and curb to allow passage of the vehicle track. A filler portion of concrete material passes rearwardly through a passageway in the roadbed slip-form above the final top surface of the roadbed and such filler portion of concrete material is transferred transversely outwardly to fill such a gap rearwardly of the vehicle track. Finally, the top surface of the material so transferred and that of the roadbed from where such material was transferred are smoothed.
