Abstract
This study evaluated the effects of acrylonitrile- butadiene- styrene (ABS) polymer on the paving mixtures made with calcium carbonate (CaCO3) as a common filler and Blowdown (B) waste as a sustainable filler. Both mixtures, Unmodified and ABS-modified containing both fillers were subjected to Marshall stability (MS), Marshall Quotient (MQ), tensile strength (TS), tensile strength ratio (TSR), cracking tolerance index (CTindex) and deformation strength (DS) in Kim tests. Statistical analyses of the results show that a B-mixture owned higher MS and DS, with lower TSR and CTindex than CaCO3 mixture, while ABS modified-B mixture depicted higher marshall stability, cracking and fatigue resistance with lower moisture, rutting resistance comparable to the ABS-modified CaCO3-mixture. In addition, B-mixture is a cost-effective solution and eco-friendly than CaCO3 mixture for pavement application since its properties located within the specification's limits
