Formatted abstract

 Many design methods for soil-cement pavements have been developed and used by road authorities. Without exception, they are empirical and take no account of the stresses which cause failure, or the resistance of soil-cement to these stresses. While most of these pavements have been satisfactory, some have failed in service. A rational design method should reduce the number of pavements that fail. 

Present design and construction methods produce soil-cement that usually breaks up into interlocked blocks which act as a flexible pavement. The writer considers the stresses and proposes that soil-cement pavements can be constructed as finite, rigid slabs.

 Both static and fatigue stresses have been considered within this thesis. La bora tory specimens were studied under both types of loading and the results were used in the pavement design. 

Near Barcaldine, in central western Queensland, a group of experimental, stabilized pavements was constructed in 1962. Because these pavements have been well documented, the insitu clay was chosen by the writer for his series of tests. A design for a pavement on this material has been included.


It has been concluded that the existing methods of estimating the stresses in slabs are not valid for soil-cement. An approximation is suggested. By using suitable construction methods and incorporating shrinkage joints, the writer proposes that soil-cement slabs can resist the stresses which will be applied during their lifetime.
