Development of Pervious Paver Block by Using Rap and Rice Husk Ash

Abstract

This specific kind of concrete is characterized by its interconnected pore structure and substantial void content or porosity, often ranging from 15 to 35% in terms of volume. Pervious concrete has the potential to mitigate the risk of floods, decrease storm-water runoff, attenuate noise generated by vehicle tires, and prevent glare and skidding in wet conditions by facilitating the infiltration of water via its porous structure, therefore replenishing the groundwater table. In light of the current state of the adjacent road networks, a conscientious endeavour is undertaken to develop a concrete paver with minimal permeability. Compression strength, void ratio, and infiltration experiments were conducted to evaluate the desired Mix proportions. In the current study, pervious paver blocks with a thickness of 60mm were manufactured using different percentages of RAP aggregate and rice husk ash. These blocks were specifically designed for medium traffic conditions. Consequently, the compressive strength is enhanced. Recycled asphalt pavement (RAP) aggregates provide a viable alternative to natural and synthetic aggregates for use into construction endeavours. The thesis provides an analysis of the potential use of rice husk ash residue. The compressive strength, density test, porosity, permeability, and durability of the paver block were assessed by several research investigations
