A STUDY OF SOIL CEMENT WITH CHEMICAL ADDITIVES

The best practical method of stabilization for construction of flexible pavements in Rhode Island was determined by investigating 17 soils with nine different chemical additives. The study was conducted both in the laboratory and in the field. The laboratory study dealt mainly with the selection of the most effective chemical additive for the cement-stabilized Rhode Island soils. The field study was essentially an evaluation of the effectiveness of cement stabilization with and without a chemical additive based on pavement performance. Results indicated that sodium sulfate is the most effective chemical additive. Addition of 1 percent sodium sulfate can significantly increase strength and durability and decrease frost heaving. Pavements containing soil cement plus 1 percent sodium sulfate base possess greater rigidity than those with soil cement alone. Soil cement test pavements developed cracks; an addition of 1 percent sodium sulfate did not appear to significantly influence the cracking behavior of pavement.
