PCT No. PCT/SE87/00264 Sec. 371 Date Nov. 16, 1989 Sec. 102(e) Date Nov. 16, 1989 PCT Filed May 29, 1987 PCT Pub. No. WO88/09412 PCT Pub. Date Dec. 1, 1988.A method for forming load-bearing road and ground constructions on a ground bed having a low load-bearing capacity includes assembling rigid support elements on the ground bed, forming a wearing layer above the support elements and disposing a light material having a bulk density lower than the ground bed below the support elements. The support elements are designed to be rigid so that point loads are distributed over the supporting surface of the ground bed. Before positioning the support elements, the ground bed is excavated to a predetermined depth such that the weight of the excavated ground mass in the area in which the support element is to be positioned corresponds essentially to the weight of the support element itself. By combining the heavier materials in the support elements and the light materials therebelow, the supporting structure is formed with a bulk density which does not exceed the average bulk density of the excavated ground mass so that the load exerted on the ground bed by the weight of the support structure and some of the dynamic loads absorbed by the support structure are compensated by the load reduction associated with the excavated ground mass. Any excess dynamic load exerted on the ground bed through the support structure is temporarily absorbed by the pore water pressure present in the ground bed.
