A PROCEDURE FOR ESTIMATING THE DESIGN CBR VALUE OF A DUNE SAND

The findings of the standard CBR test for granular material usually show values which are up to 5 times the field values. The latter are relevant for design purposes. Procedures adopted by several organizations recommend CBR values for dune sand, which are based on indicative properties and accordingly, the CBR values vary from 7% to 40%. It is obvious that this range cannot provide a reliable basis for design. This paper proposes an alternative method for estimating CBR values for Israel's dune sands. It has been found, that the theoretical bearing capacity concept works for estimating CBR values. This concept, while modified by in situ CBR data, provides a basis for estimating design CBR values. Finally, a relationship between the design CBR value and uniformity coefficient is given, where design CBR values of 7% and 14% correspond to uniformity coefficients of 1.1 to 2.6, respectively.(a) /TRRL/
