Abstract
A machine for texturing a paved road surface on a skew includes a bridge rig spanning the paved road surface in a generally transverse orientation with relation to the generally longitudinal orientation of the paved road surface. The machine includes a carriage assembly, which is supported by the bridge rig for traveling along the bridge rig in its generally transverse orientation. The machine also includes a texturing element, such as a broom, or the like, which is connected to the carriage assembly for texturing the paved road surface as the carriage assembly moves along the bridge rig. By coordinating the movement of the texturing element with the movement of the carriage assembly, the paved road surface is textured on a skew with a transverse tining pattern while the frame of the machine remains square to the paved road surface.
