The MDD for West African Standard (WAS) compactive effort increased with higher CKD content. The Optimum Moisture Content (OMC) for BSL and BSH compactive efforts increased up to 6% CKD content then decreased with higher CKD content. For the WAS compactive effort, the OMC generally decreased with higher CKD content.
EFFECTS OF COMPACTIVE EFFORTS ON ...
The geotechnical properties considered for this analysis include the spent engine oil content, maximum dry density, optimum moisture content, percentage fine, plasticity index using compactive effort as a deterministic parameter with compactive effort index values of 1, 0 and 1 for British Standard light, West African Standard and British Standard Heavy compactive efforts respectively.
Effects of Steel Mill Scale on the strength ...
the compactive effort for the WAS consists of the energy derived from a rammer falling through 45cm onto five layers, each receiving 10 blows. When the CBR mould is used, the WAS compactive effort is also derived from a receiving 25 blows (Osinubi 1998a, b). WAS compaction is commonly used in West Africa region.

The plasticity modulus is the product of the plasticity index and the percentage of soil fraction passing 425 µm (CIRIA, 1988). These terms are often used to show the contribution of the soil's plasticity and particle size distribution to its behaviour.

This paper presents a study on the influence of compactive effort on long term hydraulic performance of compacted foundry sand treated with bagasse ash, with specimens permeated with municipal solid waste (MSW) landfill leachate in sequence.
Influence of Compactive Efforts and Compaction Delays on ...
The results of a laboratory study on the influence of standard Proctor and West African standard compactive efforts as well as compaction delays up to 3 h on the compaction and strength characteristics of lateritic soil treated with a maximum of 8% lime (by dry weight of soil) is presented.

compactive effort for the WAS consists of the energy derived from a kg rammer falling through 45 cm onto five layers, each receiving 10 blows. When the CBR mould is used, the WAS compactive effort is also derived from a kg receiving 25 blows (Osinubi, 2006). WAS compaction is commonly used in West Africa region.
