A soil proposed for a compacted fill contains 38% fines and 62% coarse materials by dry weight. when the coars fraction has w=2.0%, its affinity of water is completely satisfied( that is,it is saturated but surface dry). The atterberg limits of the fines are LL=31 and PL=13. The soil is compacted by rolling to a pd=1.95Mg/m cubed. at w=15% Note: This is the water content of the entire soil mixture.
a) what is the water content and liquidity index of the fines in compacted mass?A civil engineer used a 30-m tape in measuring an inclined distance. The measured length on the slope was recorded to be 459.20 m long. The difference in elevation between the initial and the end point was found to be 1.25 m. The 30-m tape is of standard length at a temperature of 10ºC and a pull of 5 kg. During measurement the temperature reading was 15ºC and the tape was supported at both ends with an applied pull of 7.5 kg. The cross-sectional area of the tape is 0.065 cm2 and E = 2.0 x 106 kg/cm2. The tape weighs 0.075 kg/m and has a linear expansion is 0.0000116 / ºC. Apply corrections for temperature, pull, and sag to determine the correct horizontal distance considering a gentle slope.
