Compaction Characteristics of Modified Clay Soils with Various Proportions of Crumb Rubber

The reuse of waste material is becoming an emerging thrust area in Civil Engineering. Crumb rubber produced in abundant worldwide is reused in concrete, pavements, sports field, etc. The influence of crumb rubber, when mixed with highly compressible and inorganic clay, shows significant influence in its compaction characteristics under light compaction. Various proportions of crumb rubber were added namely 10,15,20,30,40 and 50% by weight and tested to understand its compaction characteristics. The behaviour of wet and dry of optimum side of modified soil with various percentages of crumb rubber was discussed. A model is generated to calculate the maximum dry density of the modified clay.
