Abstract

A road paver is provided with a drive, a bunker, a material conveying device, a screed comprising a tamping device and an electric heating device on the screed and/or on the tamping device, wherein a control unit is configured in such a manner that it determines, by means of a measurable electrical operating parameter of the electrical heating device on the screed and/or on the tamping device, the weight and/or the center of gravity and/or the width of the screed transversely to the working direction of the screed. A method for determining a width and/or a weight and/or a center of gravity of a screed of a road paver, comprising the steps: measuring an electrical variable of a heating device, in particular a heating power, a heating resistance or a power consumption of the heating device; calculating the weight and/or the center of gravity and/or the width of the screed transversely to the working direction of the screed by means of the electrical operating variable.
