Abstract

The STrengTh Behaviour of TranSiTional group a-2-7 Soil STaBiliSed wiTh fly aSh and lime powder recent works aimed to investigate geotechnical properties of Transitional Group A-2-7 (TGA-2-7) soil affected by the use of hydrated lime and fly ash class F, by-products from quarries and a cement factory in Jordan, to compensate for the gap in the granular distribution. host soil was exposed to various proportions of fly ash and lime powder. The blended specimens were subjected to different tests related to index properties, including Atterberg limits, compaction properties and California bearing ratio. The results demonstrate that 2% fly ash led to a reduction in the plasticity index from 19% to 10%, while lime powder reduced it from 19% to 13%. A sufficient improvement of maximum dry density was observed at 20% lime addition and increased from 15.11 kN/m 3 to 16.29 kN/m 3 . California bearing ratio that measures the strength soil linearly increased up to 10% induced by 20% lime addition.
