Abstract


Waste and rising cost of importing admixtures during construction have influenced research into better ways of recycling local waste and reduce cost of importation of admixtures.  Waste Engine Oil are checked as non-bituminous and can be incorporated into asphalt concrete mix design. Different researches have shown that some waste/by-products can be included as additive in hot-blend black-top cement to acquire specific beneficial properties. It is on this basis that this research attempts to investigate the effect of waste engine oil fraction on mechanical properties (stability) of asphalt concrete. An trial approach was embraced to accomplish this objective utilizing the Marshal Mix plan technique to get ready agent tests. Steadiness and stream were acquired utilizing the Marshal mechanical assembly. The results show that stability, obtained from the waste engine oil modified HMA concrete was better than that of the conventional (unmodified) HMA concrete buy direct addition. However, waste engine oil Blended concrete Optimized at 6% content by weight of aggregates and was the threshold, where it attain maximum values of stability.
