EXPERIMENT 9 MOISTURE-DENSITY RELATION …
Oct 05, 2002 · Modified Proctor Test is identical to the Standard Proctor Test except it employs, a 10 lb hammer falling a distance of 18 inches, and uses five equal layers of soil instead of three. There are two types of compaction molds used for testing. The smaller type is 4 inches in diameter and has a volume of about 1/30 ft3 (944 cm3),

Direct Shear Test - University of Illinois at Chicago
cemmlab.webhost.uic.eduAug 30, 2002 · The direct shear test is one of the oldest strength tests for soils. In this laboratory, a direct shear device will be used to determine the shear strength of a cohesionless soil (i.e. angle of internal friction (f)). From the plot of the shear stress versus the horizontal displacement, the maximum shear stress is obtained for a
