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...

Soil improvement by blasting charge technique is known in geotechnics as one of the efficient and inexpensive method. It can be used in preparing of underground to found road construction and buildings as well. The technique proves usefulness especially when dynamic load is applied. It is because of non-stiff or rather resilient type soil after improvement. In noncohesive or organic soil, blasting charge...

Quick and effective method of subsoil and railway substructure improvement by using explosive means (registered trade name: microblasting) allowes design and construct railways on lowered bearing soils (i.e. wetlands, marshlands, industrial by-products, municipal wastes, degraded antropogenic embankments). It is usefull and recommendable technology to construct new railways, modernization or maintenance and repairing of old ones...

Вопрос усиления грунтов оснований имеет особую значимость в дорожном строительстве, поскольку стабильное земляное полотно является одним из основных гарантов безопасности движения транспортных средств, а также долговечности и сохранности дорожной одежды или верхнего строения железнодорожного пути. На сегодняшний день существует ряд технологий, позволяющих выполнить стабилизацию слабых грунтов оснований. Сопоставление результатов...
