Özet
As a result of rapid urbanization, impermeable surfaces used in* roads, pavements, parks, and gardens cause a rapid increase in the number of urban floods and overflows. As they infiltrate rainwater into the subsurface and decrease the surface water flow, protect the underground water sources, support sustainability, and offer solutions to relieve the environmental concerns, pervious concretes gain importance with each passing day. In this study, to enhance the mechanical characteristics of them without compromising on their permeability characteristics it was aimed to make the optimum mixture design of pervious concretes which are prepared with basalt aggregates. 3 different paste volumes (15%, 20%, 25%) and 3 different aggregate gradations (10-15 mm, 5-10 mm, 10-15 mm (50%) + 5-10 mm (50%)) were used. Density, consistency, void rate, permeability, compressive strength, and splitting tensile strength tests were performed on produced pervious concrete samples. As a conclusion, it was determined that aggregate size has been directly proportional to void rate, while void rate has been inversely proportional to compressive strength in pervious concretes. It was determined that optimum design mixture was the (P25-F100-C0) mixture which was produced with 5-10 mm basalt aggregates that had 25% cement paste volume.
