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.10 p.PDFenUniversity of PretoriaMathematical relationshipsSoil strength625.732TransportationTransportation -- AfricaTransportation -- Southern AfricaSoil mechanicsPresentation
