Mass stabilisation of subgrade for road construction

The construction, reconstruction (reparation) and maintenance of roads on soft soils causes continuously problems in the Scandinavian countries. Settlements of the soft ground because of poor bearing capacity of the base causes cracks in the pavement. Traditional reparation of these faults by adding new layers just accelerates the settlements and hence contributes to new damages. In the article a construction and reparation method called the mass stabilization method will be presented. It is a environmentally friendly soil stabilization method, where the binder is mixed with the soft soil to form a homogeneous and strong layer. Due to comprehensive research and development both in binder technology and construction methods it is possible to apply it also to peat, which traditionally has been considered impossible to stabilize. New binders, such as mixtures of cement and blast furnace slag have also proved to be cost effective.
