A texturing machine is provided for the subsequent treatment of a freshly produced concrete layer having a width between left and right edges and extending longitudinally in a working direction. Left and right height sensors 92, 96 are arranged to detect a height above the freshly produced concrete adjacent the left and right edges of the layer. At least one crown height sensor 100 is arranged to detect a height above a crown of the freshly produced concrete layer 12. A controller 104 is configured to receive input signals from the height sensors and to communicate height control sensors to the height adjustable columns and to communicate a crown control system to the crown actuator. A direction sensor 110, 112 may also detect at least one of the edges of the freshly produced concrete layer. The controller 104 may receive a direction input signal from the direction sensor, and the controller may communicate a direction control signal to a steering actuator 60 of one of the ground engaging units28, 30, 32, 34 of the machine. A method of treating a freshly produced concrete layer is also disclosed. |
