The invention is characterised by mixing cement thoroughly with a microfill agent and possibly also a water reducing agent to obtain a highly-reactive a nd dry cement mixture; blending the cement mixture with at least one of the materials soil, clay or stone and possibly also water; spreading the blend o n the ground (3, 8) to a thickness of at least 15-30 centimetres; causing the blend (4, 9) that is spread out on the ground to contain sufficient cement mixture so that after compaction said blend will have a compressive strength of at least 5 MPa after 28 days; and laying a roadbed (5, 10) on the blend ( 4, 9) subsequent to said blend having cured.
