STABILIZATION OF ROAD BASES WITH CEMENT. AN INVENTORY OF EXPERIENCES IN SWEDEN

STABILISERING AV VAEGARS BAERLAGER MED CEMENT. EN INVENTERING AV ERFARENHETER I SVERIGE

This report assesses the attempts made to stabilise road bases in Sweden using portland cement. In the 1950s both the on-site and ready-mixed techniques were applied in preparing road bases using glacial gravel and sand. Test roads were built and different experimental techniques used to prevent the transverse cracking of asphaltic surface layers. A survey of the published literature on this topic is included. The use of ready-mixed road bases has effectively reduced the problems caused by transverse cracking, while cement grout filled macadam bases have diminished the frequency of reflective cracking, despite some initial construction and skilled labour problems associated with this technique. In the 1970s attempts were made to strengthen secondary, unsurfaced gravel roads using the on-site mixing technique, and several test roads were built. However the boulder content of these roads made on-site mixing a difficult process. Another problem was the presence of frost-susceptible subgrades. "Alligator" type cracking occurred but there was only a small amount of transverse and reflective cracks. Using the ready-mixed technique gave better results when the subgrades were of a higher quality. A short review is given of the results obtained in other Scandinavian countries and recommendations are put forward for further investigations into both laboratory and field work. (TRRL)
