A laboratory study on conventional CBR and DCP method in the mould

Road connectivity is essential for socioeconomic growth of the country. Construction, proper compaction and choice of suitable material for embankment are the main criterion to reduce early distress of service life of pavement. In this study conventional California bearing ratio (CBR) test (as per IS Method) and dynamic cone penetrometer (DCP) test of fly ash material are carried out in laboratory scale into the CBR mould at unsoaked and four days soaked conditions. Therefore laboratory CBR test by conventional method is checked by DCP method into the mould which is always appreciable and a good alternative for practicing engineers and researchers, and a comparison is made between the two methods. Tests were carried out for different parameters, like maximum dry density ad optimum moisture content obtained from different Proctor energy levels, different degree and mode of compactions and deviation of moisture contents from optimum condition. In most of the cases, laboratory DCP CBR is higher than conventional CBR, and higher values are also reached in the case of dynamic compaction.
