Claim:
A method for determining a compaction degree of a surface segment of a traffic surface that is to be compacted, where said surface segment which is to be compacted comprises a deposited layer of a hot material, particularly asphalt, and where said material will continuously cool down after deposition, said method including the following steps: a) passing over the deposited layer of the surface segment to be compacted, by use of at least one compacting machine, b) determining positional data of a position of the compacting machine by use of a positioning system, c) defining a current partial surface of the surface segment of the deposited layer in dependence on the position of the compacting machine and at least on a dimensions of the compacting machine, said current partial surface consisting of a plurality of subsegments which have already been passed over, wherein a size of the current partial surface and/or of the subsegments of the current partial surface are variable or that a position of the subsegments in the current partial surface is variable, and wherein the size of the subsegments of the current partial surface and/or the position of the subsegments in the current partial surface are determined in dependence on an overlap of a previous partial surface with at least another previous partial surface and/or with at least one subsegment of previous passes, d) measuring and/or picking up parameters at the position of the compacting machine, which parameters are useful in the determining of a compacting effect, and storing said parameters together with the position data, e) assigning the parameters to the current partial surface or to all subsegments of the current partial surface, f) computing, from said parameters, a current compaction degree for the current partial surface or each subsegment of the current partial surface, g) repeating the steps a) to f) in such a manner that, in step f), the parameters which have been stored during previous passes for the current partial surface or each subsegment are each a part of the parameters to be included in the computation.
