“…It was observed that the MDD increased from 1.512 g/cm 3 (at Reduced Standard Proctor compaction) to 2.000 g/cm 3 (at Modified Proctor compaction), while OMC reduced from 29.1% (at Reduced Proctor compaction energy) to 12.1% (at Modified Proctor compaction energy). These trends are in agreement with Lambe (1958) and Yusoff, et al (2016). These authors attributed the variation to soil structure and electrical double layer theory.…”

“…The authors worked on a trashed clay soil, stabilized with calcium hydroxide, to obtain optimum compaction energy that will give the highest Unconfined Compressive Strength (UCS), considering Standard Proctor energy level, modified Proctor energy level, and energy level of 4000 (kN-m)/m 3 . Yusoff et al (2016) Effect of remoulded density on agricultural soils was also studied because of the negative effect high density has on rate of crop growth. Mada et al (2013) worked on effect of soil compaction on soil physical properties.…”

Effect of density on consolidation and creep parameters of a clay soil was investigated using a soil classified according to Unified Soil Classification System (USCS) as Clay of High plasticity (CH) and composing majorly of secondary minerals, including montmorillonite. The air-dried soil was compacted at five different compaction energy levels (Reduced Standard Proctor compaction energy, Standard Proctor compaction energy, West African compaction energy, Reduced Modified Proctor compaction energy, and Modified Proctor compaction energy). Specimens for consolidation tests were molded at the five different compaction energy levels (densities). The consolidation parameters (initial void ratio, compression index, and preconsolidation pressure) were observed to be empirically related to the compaction energy. The creep parameters (i.e. primary compression index, secondary compression index, and magnitude of creep) were observed to increase with increases in loading to 387kN/m2, after which the values decreased. Curves resulting from these relationships were observed to increase with increases in compaction energy level and tent towards straight line at Modified Proctor compaction energy. Maximum magnitude of creep estimated for three years was observed to reduce from 455.5 mm at Reduced Standard Proctor compaction energy through 268 mm at West African compaction energy to 247.4 mm at Modified Proctor compaction energy levels.

“…It increases soil swell potential, and it is undesirable. Yusoff et al (2017) investigated the effects of compaction energies on different geotechnical characteristics of laterite soil and kaolin to better understand the effects of compaction energies on the soil. By compacting specimens with two different levels of impact energy, one can estimate the dry unit weight over a wide range of moisture content as well as the Unconfined Compression Strength parameter.…”

Influence of Compaction Energy on Cement Stabilized Soil for Road Construction

Compactness is an important feature to ensure subgrade stability where temperature and water infiltration exist in semi-arid areas. Chemical soil stabilization can improve soil properties. This research studies the impact of compaction energy on stabilized subgrade soil and how to improve its geotechnical characteristics in the experimental tests on both unstabilized and stabilized soil samples by adding ordinary Portland cement and sulfate-resistant cement, in percentages by the soil's weight, in order of identification and classification, to the strength properties tests: compaction at multiple energies, CBR, and UCS. A test protocol was followed to assess the relationship between cement soil treatment, mechanical characteristics, and compaction parameters at different energy levels. Findings show that the higher UCS values were recorded with an increase in compaction energy. The MDD of cement stabilized soil increases as compaction energy increases, whereas the OMC decreases, the UCS improves, and the CBR increases. These improvements have a positive influence on the performance of soil used as a subgrade. The combination of cement stabilization and a high compaction level for subgrades using weak soil can improve strength parameters throughout any phase of earthwork construction design that leads to strengthening subgrades, reducing the thickness, and, as a result, low construction cost.

“…Joel and Joseph [32] investigated the influence of compactive energy on the strength indices of lateritic soil stabilized with calcium carbide waste and reported an increase in CBR and UCS of the soil. The effect of different Compactıon Energy (Standard Proctor and Modified Proctor) on geotechnıcal propertıes of Kaolın and Laterıte was investigated by Yussof et al [33]. The finding from the study showed that strength characteristics of Kaolin and Laterite increased with increasing energy level.…”

This study investigated the statistical significance of compactive efforts, steel slag and cement on the geotechnical features of the laterite soil. Steel slag and cement were incorporated into the soil. Some geotechnical tests were performed on slag-cement-soil samples. Findings showed that the liquid limit (LL) and plasticity index (PI) decreased with increasing slag content, while cement addition increased LL and PI. As compactive efforts increased, MDD and CBR increased with a corresponding decrease in OMC. A more significant influence of the compactive effort and steel slag on the geotechnical features of the laterite than that of cement was observed.
