This thesis is divided into two sections, the first section deals with compacted, dry crust clay in road embankments. The second section deals with the design and construction of an instrument to measure the settlements and horizontal strains in compacted fills. The tests performed on the compacted clay are divided into two groups: a) Tests on laboratory treated and compacted samples. b) Tests on field compacted samples. Triaxial tests are used with low friction end plates and the pore-pressures are measured by using a ceramic probe at midheight of the samples. Standard consolidation and dissipation tests are performed on laboratory compacted samples and tests are performed to study the increase in strength with time on compacted samples. Data from compacted fills are presented and discussed, soil parameters are choosen and stability calculations are performed. Pore-pressures are measured in a compacted fill, and the results are reported. A new instrument for the measurement of vertical settlements and horizontal strains is presented with a complete field measuring system. Examples from actual measurements are given. Conclusions are drawn at the end of each section. Curves, tables and photographs are given in the Appendix.
