DETERMINATION OF CBR
Ғылым және технология
In this video , I had given full detail of procedure as per AASHTO Designation: T 193-99 -2003 for determining CBR.
California Bearing Ratio (CBR) test was developed by the California Division of Highway as a method of classifying and evaluating soil-sub grade and base course materials for flexible pavements. CBR test, an empirical test, has been used to determine the material properties for pavement design.

The soil sample used in the CBR test should pass from 20 mm size and retained on 4.75 mm size. Is it correct? Or, the soil pass from 20 mm sieve can be completely used without control the 4.75 mm sieve. Could you explain this clearly please? Thank you.

If all material passes a 19.0-mm sieve, the entire gradation shall be used for preparing specimens for compaction without modification. If there is material retained on the 19 mm sieve, the material retained on the19 mm sieve shall be removed and replaced by an equal amount of material passing the 19.0-mm sieve and retained on the 4.75-mm sieve obtained by separation from portions of the sample not otherwise used for testing. From a sample having a mass of 35 kg or more, select a representative portion having a mass of approximately 11 kg for a moisture density test and divide the remainder of the sample to obtain three representative portions having a mass of approximately 6.8 kg each.

175 height is including with collar which is 50 mm so while calculating volume , you have to take height 175 - 50 = 125 mm

In highway 19 mm sieve is very important , in all gradation you will find 19 mm sieve , 20 mm sieve is never used in highway, it is used in concreting work only, 19 mm sieve is used in soil , CTB , BM , DBM , BC , SURFACE DRESSING , STONE MASTIC ASPHALT, BITUMEN COLD MIX ,DLC & PQC.I think you got your answer.
