Verfahren zur Herstellung einer wenigstens zweischichtigen Asphaltkonstruktion und Asphaltmischgut hierfür

摘要

The invention proposes a method for solving the problem of producing an at least dual-layered asphalt structure that can also be installed cost-effectively and in adverse weather conditions. In such a method, this at least dual-layered asphalt structure comprises at least one lower layer and one upper layer produced using a road paver that has at least two screeds arranged one behind the other, or using a road paver combination of at least two road pavers arranged one behind the other. For the at least one lower layer, an asphalt mix is used which comprises stone chippings, sand, filler, and binder, with a chipping content having an aggregate of > 2 mm between approximately 55 m.% and approximately 80 m.%, a sand content of natural and/or crushed sand having a grain size of > 0.063 mm and <= 2 mm between approximately 6 m.% and approximately 20 m.%, a filler content having an aggregate of <= 0.063 mm between approximately 10 m.% and approximately 25 m.%, and a binder content in a range of between approximately 4.5 m.% and approximately 6.7 m.%, the total mass of the asphalt mix, including any further additives, amounting to 100 m.%, and the asphalt mix for the at least one lower layer having a maximum grain size of up to approximately 32 mm.
