Abstract: In recent years, the demand for sustainable and eco-friendly construction materials has increased due to rapid urbanization and environmental concerns. Concrete paver blocks are widely used in pavement construction because of their durability, strength, low maintenance, and ease of installation. This review paper focuses on the performance evaluation of environmentally sustainable precast cement concrete paver blocks by incorporating waste materials such as fly ash, plastic waste, coconut fibre, construction and demolition waste (CDW), and recycled aggregates. The study reviews various research works to understand the effect of these materials on mechanical properties such as compressive strength, flexural strength, abrasion resistance, and durability. The review also highlights the role of fibre reinforcement, including coconut fibre, polypropylene fibre, and polyester fibre, in improving crack resistance and toughness of paver blocks. Additionally, the concept of permeable and porous paver blocks is discussed, which helps in reducing surface runoff and improving groundwater recharge in urban areas. The findings from previous studies indicate that the use of alternative materials not only improves sustainability but also enhances certain performance characteristics of paver blocks. However, the study also identifies key research gaps such as lack of long-term field performance data, limited studies on combined use of multiple materials, and absence of standardized guidelines for sustainable paver block design. Therefore, future research should focus on optimization of mix design, field implementation, and development of codal provisions. Overall, sustainable paver blocks have great potential to contribute towards environmentally friendly and cost-effective pavement construction.
