“…This has consequently resulted in a Hicks and Monismith (1971) on investigations conducted on unbound granular soils. Omotosho (2004) also provides similar observations based on studies conducted on laterite soils of Nigeria. The addition of fines has also resulted in a corresponding decrease in the specific gravity from 2.65 to 2.45.…”

The focus of this study was on correlating the effect of grain-size, maximum dry-density (MDD), field moisture content, and the void ratios on penetration measured using the dynamic cone penetrometer (DCP) for laterite soils blended with fines. Tests were performed on soil samples compacted to MDD for moulding water contents set to the optimum moisture content (OMC), dry of OMC, and wet of OMC un-soaked condition. The results indicated that an increase in the fines-content caused a decrease in the MDD, and an increase in the OMC and the DCP penetration. Regressions were developed correlating various parameters.

“…On the other hand, at CC = 50%, the fine particles reduce the effect of the moisture content and produce higher cohesion force which require more moisture content to reposition the coarse particles and reach higher MDD [17,18]. The OMC results agreed with outcomes from Wang et al [5,6], Abu-Farsakh [7] and Omotosho [9]. However, the regressive relationship between OMC and CC can be related to the fine content where the highest fine content, the highest water required to minimizing the effect of the cohesion thus achiving the MDD point [17].…”

“…In the OMC comparison, the outcomes from Omotosho [9] and Dafalla [11] showed close value to the current study where the moisture content was less than 30% compare with 45.5 % in Santos et al [12] results. And the material which used in both Omotosho [9] and Dafalla [11] were close the material in current study compare with the ash soil mixture from Santos et al [12].…”

“…Similar behaviour observed on Wang et al [5] where MDD increase with an increase CC from 10 to 50% then decrease with further increment of CC from 60 to 80%. In addition, Wang et al [6] and Omotosho [9], indicated that the increment of the coarse content caused decrement of OMC. Wang et al [5] stated that there is non-linear relationship between the increment of the coarse content and OMC.…”

“…The previous researchers studied the effect of the coarse content on compaction parameter using gravel size [5,9,10]. Other researchers correlated between CC and compaction parameters using different fine materials such as bentonite [11], Fly ash with soil mixture [12][13][14].…”

The compaction is a mechanism to densify the loose soils. The maximum soil densification can be achieved by optimization of the desirable optimum moisture content (OMC) and maximum dry density (MDD). The maximum dry density and the optimum moisture content were affected by several parameters. The coarse content (CC) is one of these parameters. This paper studied the effect of the coarse content on the compaction parameters (MDD, OMC). Several sand-kaolin mixtures had coarse content ranged from 30 % to 80 % and moisture content ranged from 12% to 20% were used to inspect the relationship between CC, specific gravity (Gs), MDD, OMC, and bulk density. The results presented five empirical correlations with coefficient of determination (R2 ≥ 0.98) between CC, Gs, MDD, OMC and bulk density. The comparison between the current study and previous researchers indicated that both soil type and moisture content have significant effect on the efficiency of the empirical correlation equations between the maximum dry density, specific gravity, and coarse content. The results indicated a linear relationship between coarse content toward maximum dry density and specific gravity where both MDD and Gs increased with an increase CC. In contrary, the results showed non-linear relationship between optimum moisture content and coarse content where OMC decrease with an increase CC.
