Concrete road construction machine

摘要

The machine is for continuous construction of two concrete layers (11,12) in a roadbed. It has an internal vibrator, and a second vibrator (9) between the levelling beams. The second vibrator is a tubular vibrator, which acts on the second concrete layer (12) from above, and generates vibrations horizontally and at right angles to the direction of travel. A dowel driver (10) is located behind the second levelling beam (6). Both the tubular vibrator and the levelling beam are height-adjustable.
