Web17 Mar 2002 · The US Army Corps of Engineers has published many Engineer Manuals that can make you more than satisfied since they are based on current practical applications and have sustantiable references for further reading. For example, N values has been used mainly for sands to correlate allowable bearing pressure. WebCalifornia bearing ratio is the percentage of stress a soil specimen can resist for a certain amount of penetration relative to the value of stress of which a standard soil could resist. Basically, the value is an indicator of the strength of the soil. CBR= P s P std. ×100% C B R = P s P s t d. × 100 %

WebLike the SPT, the Dynamic Probing Super Heavy (DPSH) uses a hammer that delivers energy to a rod string by dropping a weight of 63.5kg from a height of 760mm. Unlike the SPT, a solid cone is driven instead of a split spoon sampler. Soil samples are not brought to the surface so a continuos record of penetration is recorded without tripping tool ... Web5.13 CBR value from DCP data • The DCP is often used for the determination of the in situ CBR. • Various correlations exist depending on the soil type. A site specific correlation should be carried out where possible. • The correlation is not as strong for values ≥ 10 blows/100 mm (10 mm/blow), i.e. CBR > 20%.
