Table-1: Trial Mix 50:50 M4 40:60 M3 30:70 M2 Flyash is in terms of dry weight of WRP 20:80 M1 Remark Flyash:WRP Mix

Table:2 WRP and Fly Ash Mixes M2, M3 : Unconsolidated untrained trained test Falling Head permeably test Permeability requirement 10 -7 cm/sec. Flyash on higher side and slushy due to high moisture content - - 17.20 16.09 M4 Stable 1.75x10 -5 25 85 15.60 16.66 M3 Stable 1.78x10 -5 30 60 14.40 17.84 M2 Flyash on lower side - - - 14.00 18.64 M1 Remarks K (cm/sec.) Ø (°) C (kPa) OMC(%) MDD(kN/m3) Mix

Table 3 : WRP Fly ash and cement mixture *Cement used as dry weight of WRP and fly ash (mix M3) ** confirm permeability requirement and posses considerable shear strength 2.38x10-7 30 120 7 M3 C2** 3.30x10-7 33 100 5 M3 C2** MDD and OMC value for the mixes consider same as M3 2.39 x10-6 36 25 3 M3 C1 Ø (°) C(kPa) Remakrs K(cm/sec.)
