The reuse of reclaimed asphalt pavement (RAP) instead
of aggregate reduces natural aggregate consumption in concrete mixtures
and production cost of concrete. Waste crushed asphalt’s water
absorption is less than the water absorption of natural aggregate owing
to the bituminous structure; this reduces the water demand in fresh
concrete. In the present study, the optimal use of RAP particles as
aggregate in concrete roads has been measured. In the tests, concrete specimens
have been produced with 0–12 mm waste crushed asphalt at the replacement
ratios of 0, 25, 50, and 100%. The destructive, nondestructive, and durability
tests have been carried out on hardened and fresh concrete specimens to identify
physical and mechanical properties. The slump values were obtained in fresh
concrete and ultrasonic pulse velocity (UPV), and compressive strengths were
obtained in concrete at the end of 3, 7, and 28 days. According to Experimental
results, asphalt waste caused the reduction of strength, physical, and Mechanical
properties.
