The Öresund link project involves a number of connecting roads and bridges, of which the main road on Swedish ground is Yttre Ringvägen around Malmö. Parts of this road will be built where the bearing capacity of the existing ground is too low. Some of the contractors handle this by lime or cement stabilisation of the uppermost soil. Two of these stabilised sites were investigated with geophysical methods aiming at validating the efficiency of the stabilisation process. DC-resistivity was tested as a method for checking the homogeneity and depth penetration of the stabilisation, and SASW for determining the increase of the stiffness of the subsurface when stabilised.
