A system comprising a temperature measurement device for repeatedly detecting temperature values of a pavement laid by a paver. The system is configured for ascertaining a temperature value for a specific measuring point at at least two different moments in time by means of the temperature measurement device, the specific measuring point lying in an area of the laid pavement. The system additionally comprises an evaluation unit, the evaluation unit being configured for determining a cooling behavior of the laid pavement. This is done by making use of the at least two different temperature values that have been detected for the specific measuring point at the at least two different moments in time.
