Pervious concrete is made up of a layer of mortar, coarse aggregate, and bonding that creates a structure that resembles a honeycomb. The fact that pervious paving has holes in it that let water seep through to the underlying materials underneath is one of its key features. Additionally, it lessens water pollution and peak stormwater flow while encouraging groundwater recharging. The primary goal of this study is to replace cement with GGBS, which makes it environmentally friendly, while also aiming to strike the ideal balance between strength and permeability. Utilizing a by-product like GGBS is a sustainable construction practices, which results in lower CO2 emissions. In this paper, 10%, 20%, and 30% of GGBS have been replaced to cement. HDPE plastic fiber with length 18 ± 2 mm, which is obtained from the used HDPE cement bags, is used as a reinforcing material. Different proportion of plastic fibers 1%, 1.5%, and 2% was added in pervious concrete trial. The specimens were casted and examinations like the compressive strength test, infiltration test, flexure strength test, and impact test were conducted to determine its mechanical properties. When GGBS was optimized, the mechanical properties of pervious concrete were boosted. Based on the test results, the optimum dosages for GGBS are 20%. Compressive strength was 23.44% more than in the control group. Adding 1.5% HDPE fiber was the most beneficial to improve the flexure properties. It is 41.68% greater than control mix, but infiltration rate decreases with increase in fibers. Considering 1.5% HDPE fiber-reinforced concrete to ordinary concrete, it was found that the impact strength increased to more than 100% for the first fracture and 85.52% for the final failure, respectively. It has been demonstrated that the mix GH-7 (20% GGBS with 1.5% HDPE fiber) has better compressive strength, flexural strength, and impact strength, and thus can be utilized as a paving material.
