Paper presented at the 32nd Annual Southern African Transport Conference 8-11 July 2013 "Transport and Sustainable Infrastructure", CSIR International Convention Centre, Pretoria, South Africa.
Mathematical relationships between soil strength parameters are established. From only a
few laboratory tests, performed within a twenty four hour period, the assessment of a soil’s
achievable condition and possible use prior to placement is enabled. From the DCP test
with a moisture content reading the relative compaction, soaked CBR and density of a
compacted layer can be assessed. In an appendix the derivation of mathematical
relationships, together with a comprehensive table of these relationships is given.
