On strength characteristics of unbound aggregates / Ahmad Saifunazif Mat Yatim

This study is limited to laboratory investigation of the strength and degradation characteristics of course aggregates. The testing carried out were the CBR and MBR tests, large shear box tests and compression test. The purpose of this study is to examine the influence of confinement pressure on the strength characteristics of the aggregates tested. In addition this study was also carried out to examine the influence of compaction on the shear strength value of the aggregates and its degradation characteristics . Experimental work in determining the degradation and strength characteristics was carried out under dry condition using aggregates taken from the Damansara quarry . The aggregates were predominantly granite. Three different gradation namely, well graded, uniformly graded and gap graded were used.
