Abstract :Today, due to the increasing construction activities, the evaluation of waste materials has also accelerated. Recycling concrete and road materials provides environmental benefits as well as economic benefits. In this experimental study, it was aimed to use the scraped asphalt pavement as aggregate in the concrete mix. Different proportions of limestone, basalt and scraped asphalt were used as aggregates in the produced concrete samples. CEM I 42.5 R type cement and a certain amount of replacement fly ash were used as binder, and a polycarboxylate based chemical additive was used to ensure easy workability and appropriate molding of the concrete. Pressure test was applied on the produced samples, and the results showed that the use of scraped asphalt material as aggregate reduces the compressive strength of the concrete, but its use in appropriate proportions can be promising.
