Abstract
Pervious concrete is an eco-friendly alternative and is beneficial to providing good rainwater drainage in order to prevent flooding. But the application is limited to lower trafficked roadways and often times disregarded due to its low strength capabilities. This study investigates on the effect of High-denstiy Polyethylene as partial replacement of coarse aggregates on the physical and mechanical properties of Acrylic Polymer Pervious Concrete (AcPPC). Two different coarse aggregate sizes were evaluated which are ½” and ¾” with varying ratios of 10%, 20%, and 30%. It was determined that the partial replacement of recycled HDPE caused an increase in the porosity and permeability of the AcPPC. However, it decreased the AcPPC’s compressive and flexural strength. Only the ½” 10% HDPE modified Pervious Concrete with 15% Acrylic Additive (PCHA) achieved a compressive strength that is within the range of the acceptable compressive strength for pervious concrete. While for the flexural strength, both the ½” 10% PCHA and ¾” 10% PCHA was within the standard values for flexural strength of pervious concrete. Thus, making the ½” 10% PCHA as the optimum mix in this study. The application of PCHA is limited to typical application of a pervious concrete.

Over the decades, human population continues to grow and expand
Only the controlled mix is within the density for a typical pervious concrete while all the Pervious Concrete with 15% Acrylic Additive (PCHA) are below this range and can be said that it is a lightweight concrete
Summary
Human population continues to grow and expand. As the said population increases, advances in technology continuously happen. Breakthroughs in technology happen at a frequent rate. One product of today’s innovation in technology is the paving of roads. These said roads are made of impermeable surfaces such as asphalt, concrete, traditional stone, and brick, among other possible pavers. These impermeable or impervious concrete surfaces do not allow water to pass or penetrate through. It is very common to see our roads as paved surfaces, even in rural regions
