Abstract:
A camber adjustable screeding device. The camber adjustable screeding device is arranged between two adjacent paver screed boards (1-1) on a paver screeding device (1) or is arranged at an end portion of the paver screeding device (1). The camber adjustable screeding device comprises an adjustable screeding unit (2). The adjustable screeding unit (2) and the adjacent paver screed board (1-1) close to a central position of the paver screeding device (1) form a first rotational movement pair (4). A first camber adjustment device (3) for cooperating with the first rotational movement pair (4) to adjust camber of the camber adjustable screeding device is arranged between the adjustable screeding unit (2) and the paver screed board (1-1) adjacent thereto. The camber adjustable screeding device effectively eliminates the specific problem of a camber position in road surface adjustment deviating from the central position of the paver screeding device to either side or inaccurate positioning on either side during reconstruction of old roads.
