A CBR value of 2 is usually found for clay, high-quality sub-base will have CBR values between 80 and 100, and some sands may have values around 10. The CBR testing can be applied to soils with a maximum particle size of 20 mm. For soils with bigger particles, other types of bearing capacity can be used like the Plate Bearing Test. ...
Jun 04, 2015 Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology m and the uniaxial compressive strength C 0.Lithology is commonly derived during log analysis, so m may be estimated Table 1.What is needed still is an initial measure of rock strength provided by C 0. C 0 can be estimated from porosity or sonic velocities, but

Moisture condition value MCV and chalk crushing value CCV This apparatus is used to measure the minimum comparative effort required to produce near full compaction of a soil, and the rate at which a sample of chalk lumps are crushed. The unit can be used to classify chalk as a fill material with saturated moisture content.

shear stress is the shear strength of the soil for the particular value of the normal force N or normal stress NA applied to the soil, where A is the cross sectional area of the soil sample. Fig. 8.8 shows that a dense sand has a greater shear strength than a loose sand and this strength is reached at a smaller value of the displacement.

In addition, the test will identify those chalks susceptible to crushing and which may produce weak unstable fill during construction. The crushing values of the sample is defined as one-tenth of the slope of the straight section of the line resulting when penetration is plotted against the logarithm of the number of blows. As the rate of crushing increases the slope of the line increases and a soft chalk will therefore have a higher crushing value than a hard chalk.
