In this process, the access protection is moved from a storage position to a functional position in which the access to the operating platform is blocked by the access control.

Abstract: The disclosure refers to a method and a road finisher for creating a temperature field of a newly laid paving layer corrected for interfering-related temperature measurement errors. In accordance with the disclosure, it is recognised that when the paving layer is paved, a measuring point is covered by an interfering object at a first time if, contrary to an expected material-specific cooling at a later second time during paving at the same measuring point, a larger temperature value particularly lying within a nominal temperature range than a temperature value measured to the preceding first time is measured, wherein instead of the temperature value detected at the first time a new temperature value is assigned to the measuring point in the temperature field.
