On the replacement of cupola slag we obtained the result that, on the percentages of 10, 20, 30 and 40 we have the Va values of 4.8, 4, 4.8 and 3.2 % which satisfies the morsth requirement of 3-5% and further we observed that the gradual decrease in the Va values up to 100%. So that for Va the replacement of cupola slag up to 40 % will satisfies the morsth requirement.

Higher the stability of the mix, greater will be the strength of surfacing. Stability values of semi dense bituminous concrete mix at 60ºC on replacement of quarry dust by cupola slag from 10 to 100 percentages will give the stability of 12.62 kN,19.03 kN,14.65 kN,9.53 kN,9.52 kN,8.43 kN,7.42 kN,5.56 kN, 5.56 kN,3.48 kN respectively. So that the replacement of cupola slag up to 60% will satisfies the morsth requirement of 8.2 kN. Flow value
On the replacement of cupola slag we obtained the result that, on the percentages of 10, 20 and 30 we have the flow values of 3.67, 3.32 and 3 mm which satisfies the morsth requirement of 3-5 mm and further we observed that the gradual decrease in the flow values up to 100%. So that for flow, the replacement of cupola slag up to 30 % will satisfies the morsth requirement.
X. CONCLUSION Fig 10.1 Increase in Stability by Replacing Cupola slag
From the overall all study, we have observed that the replacement of cupola slag in place of quarry dust will improve the various properties in Semi Dense Bituminous Concrete Mixes. From this overall study,
For the value of Va, the replacement of cupola slag up to 40 % will satisfy the morsth requirements.
For the value of Vma, the replacement of cupola slag up to 60 % will satisfy the morsth requirements.
For the value of Vfb, the replacement of cupola slag up to 30 % will satisfy the morsth
