Abstract

Use of recycled aggregate in concrete-mix provides many advantages for waste management; more efficient energy and natural resource use, ecological protection, and lower CO2 emissions. This study investigated the use of either 15% or 20% Reclaimed Asphalt Pavement (RAP) by weight in the production of Roller Compacted Concrete (RCC), replacing with coarse aggregate, and the effect on drying deformation and freeze-thaw resistance. After the freeze-thaw cycle, a flexural test was applied to the specimens to investigate the effect of freeze-thaw resistance on the flexural strength of specimens. Drying deformation of the control mixture was found to be 0.05% (500 microstrain) at the end of the 112th day and 600 microstrain in the mixtures containing 15% and 20% RAP. Weight loss was recorded as 2% in all mixtures. An average of 73% of the durability factor was determined in all mixtures at the end of 300 cycles. This study shows that if RAP-containing materials are used up to 20% in the RCC mixture, no significant difference in terms of freeze-thaw resistance occurs. When the effect of the freeze-thaw cycle on flexural strength was investigated, a reducing effect of about 7% in control mixtures and 17?22% in the RAP-containing mixtures was found.
