The California Bearing Ratio Test(CBR test) is a penetration test that can be performed in the laboratory or in-situ. They can be considered as small scale bearing tests in which the ratio of penetration to the size of the loaded area is much greater than in bearing tests.

The mass density of soil solids typically ranges from 2640 to 2750 kg/m3. Where mass or mass density values (g, kg, or kg/m3) are given or measured, they must be multiplied by g (9.81 m/s2) to obtain weights or unit weights before performing stress calculations.

The Atterberg of Liquid Limit Testing determines the water content at which soil changes from a liquid to a plastic state. A soil sample places into a cup of the liquid limit machine and separates into two halves using a grooving tool. The crank on the machine rotates so that the cup holding the sample strikes the base of the test machine.

Crusher dust is added to the soil at varying proportions like 20%, 30% and 40% by the weight of the soil sample throughout. Consequently, specific gravity, particle size distribution and Atterberg limits tests were carried out to classify the soil. Based on the results, the soil sample obtained was identified as 'fair to poor' soil type.

The plastic limit roller consists of rigid acrylic top and bottom roller plates, covered with sheets of SAA-9 adhesive backed absorbent paper. The paper adds no fiber to soils samples. The soil samples roll between the movable top and fixed bottom plates until the top plate contacts the 1/8″ side rails. This prevents further thread size reduction.

Atterberg soil indexes are calculated from the test results of liquid and plastic limits tests to classify soil types and properties: Plasticity Index, or PI, is the plastic limit subtracted from the liquid limit and indicates the size of the range between the two boundaries. Soils with a high PI have a higher clay content.

it seems too broad of a range in phi for a given pi to me to be of any real use other than very generalized statements. if you estimate a phi of say 30 from the chart, the range varies to either side of that by 6 or 7. well heck a range of 23 to 37 doesnt tell you anything. seems more reasonable to use atterbergs along with gradations to check .

Shrinkage = volume after compaction/volume before excavation. Both the loose and compacted volume are calculated from the bank volume. Example: If you are excavating dry clay it is listed as having a swell of 50% and a shrinkage of -10%. That means that for every 1 cubic metre/yard of material that you excavate the volume increases by 50%.
