Paving The Future With Sustainable Paver Blocks

Abstract

The accumulation of waste tires poses a significant global environmental challenge due to their non-biodegradable nature and the limitations of traditional disposal methods like landfilling or incineration. This study presents a sustainable solution by developing novel paving blocks manufactured entirely from shredded waste tire rubber bonded with an advanced polymer-resin matrix, eliminating the need for conventional aggregates (sand, gravel) and traditional cement-based binders.

The primary objective was to engineer a durable, eco-friendly construction material that effectively repurposes 100% of the tire waste. Various processing techniques and resin-to-rubber ratios were investigated to optimize the material's mechanical properties, including compressive strength, flexural strength, density, and abrasion resistance.

Laboratory results indicate that while the compressive strength of the 100% rubberized blocks is lower than that of conventional concrete pavers, the material exhibits superior toughness, high impact resistance, improved sound absorption, and enhanced skid resistance—properties crucial for specific applications like pedestrian walkways, playgrounds, and low-traffic areas. The flexibility and energy-absorbing capacity of the rubber matrix significantly reduce the risk of brittle failure and enhance user safety.

The manufactured blocks also demonstrated reduced water absorption compared to traditional concrete, suggesting improved durability and resistance to freeze-thaw cycles. This research confirms the technical feasibility and environmental benefits of producing functional, high-performance paving blocks solely from waste tire materials, offering a viable alternative to conventional materials and contributing significantly to circular economy principles and sustainable waste management practices.
