APPLICATION OF A CEMENT STABILIZED SAND AND BROKEN UP ASPHALT LAYER IN STATE HIGHWAY 76

TOEPASSING VAN BREEKASFALTCEMENTSTABILISATIE IN RIJKSWEG 76

For the reconstruction of Netherlands state highway 76 it was decided to re-use the existing flexible pavement in a cement stabilized sand and broken up asphalt roadbase layer. A mix of 87% broken up asphaltic concrete (0-40 mm), 13% sand and 5,5% blast furnace cement was advised. The mixing-in-place of the broken up asphalt (0,25 M layer), the sand (0,05 M layer) and 25,5 kg cement per sq M in two stages, as well as the execution of the compaction with rollers and tyre-rollers followed by the sprinkling of the rolled surface with bitumen-emulsion is described. It was found that after 21 days the compressive strength of the roadbase was 3 mn/sq M and therefore construction of the basecourse could commence. It is concluded that in the near future application of cement stabilized sand and broken up asphaltic concrete could compete, from an economic point of view, with ordinary construction of roadbases.
