EFFECTS OF COMPACTION DELAYS AND MULTIPLE TREATMENTS ON THE STRENGTH OF CEMENT STABILIZED SOIL

The effects of delayed compaction on the strength and durability of cement stabilized soils for base courses and subbases has been investigated. It was concluded that time delay does not adversely affect either strength or durability. However, prolonged time delay does increase the required level of compaction necessary to achieve a specified density so that it may be beyond the capability or ordinary highway compaction equipment. An example is given in the report showing how the results of this work can lead to more rational field compaction specifications for cement stabilized materials, in recognition of the fact that time delays are inherent in the construction process. /Authors/
