In the state of Tamil Nadu Sand-Gravel mix is widely used as sub - base material. Now a days sand is becoming scarce and recent findings revealed that sand may be replaced with quarry fines as sub base material. Hence a comparative study is taken up between Sand Gravel mix and Quarry Fine Gravel mix as sub base material.

Methodology

Various ratios of mixes will be prepared using sand, gravel and quarry fines from different places of Tamil Nadu and necessary laboratory tests will be conducted to find out its performance as sub-base.

Significance / Utilisation

Potential An alternate material for sand may be established
