CEMENT STABILIZED SUB-BASE LAYERS OF MEDIUM AND FINE SANDS

CEMENTSTABILISERANDE FOERSTAERKNINGSLAGER AV SAND - MODEL 2

The research project presented is a further development of the ideas published in a report from 1972 by the same author. To reduce the great demand for gravel in road construction, attempts have been made to use sand as a substitute material in the sub-base. The bearing capacity and the stability of sand is less than that of gravel. Therefore some part of the sand sub-base has to be stabilized with cement. This layer must be at least 15 cm deep to have the desired effect. Test roads with such layers were compared with a standardized road structure to determine the deformation caused by traffic load. The stabilized layer improved the bearing capacity to such an extent that both the pavement thickness and the total depth of the sub-base could be reduced considerably. The investigation indicates that in roads with heavy traffic the stabilized layer should be at the top of the sub-base whereas in other roads the economically most favourable position is at the bottom. Recommended layer thicknesses for roads are given in relation to their respective traffic load. /TRRL/
