Stabilisation case histories; cement and lime

In March, 1972 the NSW Department of Main Roads carried carried out in the field, a laboratory investigation had been done and based on satisfactory test results the field trial was commenced. However, the results in the field were disappointing and the various sections of road were reconstructed in 1976. It is thought that the failure of the pavement was due to the shrinkage of the modified material, coupled with the high rainfall that occurred shortly after completion of the construction. Water penetrated the cracks and wet the subgrade. A field investigation carried out in March, 1975 revealed that the relative compaction of the subgrade was unsatisfactory, although during construction it had complied with the specification. The only possible explanation for this behaviour is that the subgrade had swelled. This was confirmed in a laboratory investigation carried out in 1976.
