The invention relates to a milling machine having a replaceable milling drum, different types of milling drums being capable of being associated with the milling machine; and having a control unit for controlling the milling machine, machine parameters of the milling machine being settable by way of the control unit. Provision is made that the milling machine has associated with it at least one means that is designed to detect at least one characteristic feature of the milling drum; that the at least one means is connected to the control unit; and that the control unit is designed to specify for at least one machine parameter, indirectly or directly from the characteristic feature, a value to be set, and/or a setting range. The invention further relates to a corresponding milling drum and to a corresponding method. The milling machine, milling drum, and method allow the selection of machine parameters for operation of the milling machine to be simplified.

A paving binder according to the present invention is used for a paving mixture for forming a pavement, including a polyamide resin having a weight average molecular weight, as measured by gel permeation chromatography of 2,000 or more and 10,000 or less and having an area, corresponding to a component having a molecular weight of 20,000 or more and 500,000 or less, of 0.5% or more and 12% or less of a total area in a chromatogram of molecular weight distribution as measured by gel permeation chromatography. Thus, tolerance for a severe temperature condition or loading condition can be improved, while ensuring convenience from the standpoint of laying such that the laying can be made by the conventional machine composition or laying system.
