VicRoads Test Method 402.01 - Estimated California Bearing Ratio Using DynamicThis method covers the calculation of the estimated California Bearing Ratio (CBR) of cohesive soilsthe dynamic cone penetrometer described in AS 1289.6.3.2
Caution: The CBR data derived using this method should be used with care and due considerati condition at the time of the test in relation to that expected during service life of the pa

Note: The Allowable Bearing Capacity data applies to cohesive soils only and is based on bearing capacity factor Nc = 5 and FOS = 4 Approximate Cu = 0.8 x allowable bearing capacity.
Caution: The Allowable Bearing derived using this method should be used with care and consideration should be made of soil moisture condition at the time of the test in relation to that expected during service life of the foundation.
Using DCP tests for determining soil strength and allowable bearing capacity is generally considered to be of limited applicability(Ref Campanella & Robertson, 1983).
