Abstract
A road construction machine for the treatment of roadways, comprising an automotive wheel frame consisting of a steerable frontal wheel frame axle (6) and two rear support wheels (14, 16) independent from each other, comprising a driver's platform (4), for a driver of the vehicle, arranged in the area of the rear support wheels (14, 16) and on a machine frame (8) supported by the wheel frame, comprising a working means (20) arranged in or on the machine frame (8) and roughly flush with the machine frame (8) on one side, namely the so-called zero extension side (24), comprising a driving motor for the driving power required for driving the driving means (20) and for moving the vehicle, the rear support wheel (16) arranged on the zero extension side being pivotable from an exterior end position (26) projecting beyond the zero extension side (24) to a retracted interior end position (28) where the support wheel (16) does not project beyond the zero extension side, provides that the pivotable support wheel (16) is pivotable from the exterior end position (28) to the interior end position (28) by means of a gear arranged in a horizontal plane.
