Dry-lean concrete (DLC) lies below the wearing course of the rigid pavement section to overcome the major reasons for its failure, such as improper base support, seepage of underground water, and frost action. Dry Lean Concrete (DLC) is an important part of modern rigid pavement .DLC is generally manufactured with a huge aggregate-to-cement ratio, which lies below the wearing course of the rigid pavement section. In this study, aggregates obtained from tunnel muck material by crushing were used as coarse and fine aggregates in DLC and cement used is Ultratech OPC 53. From all the combination it is observed that Density is maximum(2.416 g/cc) of the mix containing cement aggregate ratio 1:15 (35% 20mm 25% 10mm 40% crusher sand) at 4.06% moisture content With respect to aggregates. Cubes were casted on the combination at which the density is maximum. It is observed that that the compressive at 3 days is 15.41 Mpa and after 7 days compressive strength is 17.67Mpa.
