PCT No. PCT/DE94/01404 Sec. 371 Date Jul. 22, 1996 Sec. 102(e) Date Jul. 22, 1996 PCT Filed Nov. 23, 1994 PCT Pub. No. WO95/14819 PCT Pub. Date Jun. 1, 1995Top layers of asphalt surfacing are laid in hot laying method in one work cycle. A first layer of a first asphalt production type hot is placed on a surface to be covered. Simultaneously with the first layer is placed a second layer of a second asphalt production type different from the first production type hot on top of the first layer. Owing to the simultaneous laying of two different and hot on hot asphalt layers from delivered mixture from an asphalt plant, thermal potential is increased and cooling delayed, therefore a considerable improvement in properties of theses two asphalt layers is achieved.
