This paper presents the possibility of utilizing reclaimed asphalt, used automobile tires and cow dung ash, which are mostly regarded as waste. These materials could be used in construction of new roads and for roads rehabilitation. Reclaimed Asphalt Pavement (RAP) was used to replaced Virgin aggregate, Crumb Rubber (CR) from waste automobile tires as modifier for bitumen and a blend of Ordinary Portland cement OPC and Cow Dung Ash as filler. 30% Reclaimed asphalt of total aggregate, 15% Crumb Rubber of total binder content, and a blend of 25% Cow Dung Ash/75% Ordinary Portland Cement of total mix, and 5.2% Crumb Rubber Modified Bitumen content were recommended for optimum performance. Loss of marshal stability was investigated on mix with the recommended optimum CRMB. The mix revealed good performance with only about 17% loss of stability after 24 hours of immersion in hot water bath, as against about 24% marshal stability lost reported in previous studies for conventional Hot Mixed Asphalt (HMA).
