  • Abstract:
  • Expansive soil is a problematic soil which usually swell on the absorption of water and shrink on removal of water, when expansive soil swells cohesion decreases. Expansive soils are predominantly found in arid and semi-arid regions of five continents in the world. These soils are constituted with montmorillonite clay mineral, which is reason for volume changes associated with variation in moisture content. Due to the undesirable volume changes in expansive soils, great distress and damages are caused to the overlying structure built on them. Hence, in this study waste EPS blocks from manufacturing units and moulded packing products from garbage were used in order to a find a possible way to reuse and reduce the waste. The procured and collected waste EPS blocks were converted into beads by hand crushing. The compressible waste EPS beads were acknowledged as recycled geobeads, basalt fiber. It is used to reduce the swelling potential of expansive soils by shallow mixing. The varying percentages of 0.25%,0.5%,0.75% and 1% of EPS and with different percentages of Basalt fiber is added independently to the clay to study the improvement in its compressive strength. The standard proctor’s compaction test is conducted on the unreinforced and reinforced clay. The results from these tests revealed that increasing the diameters and number of columns, the swelling potential is decreased due to EPS geofoam and basalt fiber.
