Abstract:
1. A road paver for laying down a layer of laying material, the road paver comprising a movable screed and a layer thickness measuring device, having at least two sensors, one of the sensors configured to define a coordinate system, the sensors being formed to carry out a distance measurement to a pavement plane at intervals and to determine a first distance between the sensor and a point on the surface of the plane that is registered by the sensors, and wherein the layer thickness measuring device being configured determine a first vector determined by combining as vectors the distance to the plane measured by the sensor configured to define the coordinate system with a change of inclination of the coordinate system during a movement of the road paver relative to the plane to; said first vector and a second vector that is defined by the distance from the one sensor defining the coordinate system to a point that lies on the surface of the newly laid layer, being communicated to the layer thickness measuring device for use in determining the layer thickness of the laying material.
