Pervious concrete is a type of concrete mixture that is usually used in pavement with a high range of interconnected voids between large aggregate particles. Herein, an experimental study was conducted in order to figure out the effect of replacing (5 %, 10 % and 15 %) of cement weight by the styrene-butadiene rubber latex (SBRL), in addition to the impact of replacing (0 %, 25 %, 50 %, 75 % and 100 %) of natural coarse aggregates by recycled ones on the mechanical properties of the pervious concrete. The focused parameters in this experimental study were divided into two parts, permeability indices (density, voids ratio and water permeability) and strength indices (compressive, splitting and flexural tensile strengths and concrete potential to degradation). Additionally, since the water permeability is the most important property in the pervious concrete, relations between water permeability and the other mentioned properties were deduced. Generally, it is noticed that the addition of SBRL positively affects the mechanical properties of the pervious concrete. However, there is a slight decrease in permeability indices. It is observed that the addition of 10 % of SBRL to the pervious concrete with 75 % recycled aggregate increased the 28 days compressive, splitting tensile and flexural tensile strength by 70.8 %, 49.4 % and 29.7 %, respectively. In addition, the results showed a reduction in the hardened voids content, water permeability and potential to degradation by 13.3 %, 11 % and 31.7 %, respectively.
