Hybrid method of subsoil improvement for road embankment foundation is described. This method is composed of two wellknown methods: dynamic replacement (DR) and microblasting (DDC) one (Deep Dynamic Compaction). The method was used for both the strengthening of the fully saturated organic subsoil as well as for acceleration of the consolidation of the organic layers. The practice ensures the expected results. A proper example on a real work is shown. The hybrid-combination of two technologies is an effective one, more over the results and the soil improvement works are relatively low cost solution compared to other conventional methods. Computer simulation of the hybrid behaviour of soil compaction needs a proper theory presented in the paper. An initial boundary value problem is formulated. A discussion is given for possible valuing the technology both in experimental stands as well as in the field measurements under short-time-load condition.
