“…There was no significant difference between M sec and M r in the final cycle for any soil (p [ 0.05). The M r values for both the Clay Loam and the Sand are within the range of values reported for similar soils in the literature [24,26,38,39].…”

The modulus and damping properties of soils in compression are a function of soil type, water content, stress history and loading rate. To model human-surface interaction with natural turf sports surfaces, stiffness and damping properties must be determined at dynamic loading rates. Two contrasting soil types, a Sand and a Clay Loam, commonly used in sports surfaces were loaded uniaxially to 2 kN at loading rates between 0.6 and 6 kN s -1 in modified dynamic soil testing apparatus. Soils were compacted prior to loading but initial cycles resulted in viscoplastic deformation, with strain accumulation with repeated cycles of loading. Ultimately a resilient, viscoelastic steady-state equilibrium with loading was established. Resilient modulus and damping ratio varied with soil type, water content, stress history and increased significantly with loading rate. The resilient modulus of the Sand soil, typical of modern free-draining sand construction natural turf sports surfaces, was significantly greater than that of a Clay Loam soil more characteristic of traditional natural turf surfaces; reducing water content caused an increase in modulus and a decrease in damping ratio in the Clay Loam soil. Determination of these properties provides initial data for the modelling natural turf surface behaviour in terms of both ball and human interactions, with further research required to determine the effect of both grass roots and leaves on mechanical behaviour.

“…It can be further observed that the penetration index for un-soaked samples (DCPI u ) for M 1 , is lower than that for M 2 , and for M 3 . This is probably due to the reason that compacted drier soils have higher stiffness and offer greater resistance to penetration in the case of sandy, silty, and clayey soils when compacted to the drier side (Kim and Kim 2006) of OMC. Table 2 provides details of regression equations developed for the prediction of DCPI values based on variations in the percentage of fines in blended laterite soils.…”

“…Also, in the field of road construction, one of the practical difficulties experienced is that, although it is required to achieve 100% relative compaction at OMC as measured using the standard proctor test, it is generally observed that the level of compaction achieved in practice is about 97% due to minor changes in water-content that tend towards 'dry of optimum' or 'wet of optimum' (Kim and Kim 2006). This is observed even in patches of pavement sub-grades that are compacted using vibratory rollers.…”

Effect of Soil Parameters on Dynamic Cone Penetration Indices of Laterite Sub-grade Soils from India

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.
