Abstract: A method for controlling a quality of a paving material distributed along a paving area using a paver includes: receiving a thermal profile of a portion of the paving area in which the paving material is distributed, and the thermal profile includes a plurality of temperature values of respective measurement points, and analyzing the thermal profile to detect segregation spots of the paving material within the portion. Analyzing includes determining a first zone of measurement points arranged adjacent to each other and having temperature values within a predetermined range, the first zone being at least partially surrounded by measurement points having temperature values out of the predetermined range, and analyzing an orientation of the first zone with respect to a travel direction of the paver. The last substep of analyzing is assigning an indication, in particular an error indication, to the portion based on the analyzing of the orientation.
