A bibliometric and content analysis of research trends in paver blocks: Mapping the scientific landscape

This study presents a novel integration of bibliometric and content analysis to comprehensively examine the research trends and scientific landscape of paver blocks. The investigation of 379 articles and reviews published across 174 journals reveals a steady growth in research output, with a notable surge in publications and citations from 2016 to 2024, underlining the increasing importance of this field. India, Malaysia, and the United States emerge as major contributors, with India leading in publication count (143) and the United States demonstrating high research impact through total citations (1,312) and citations per paper (48.59). Keyword examination highlights the prominence of sustainable materials, waste utilization, and innovative design strategies, while an in-depth review of highly cited papers unveils the potential for incorporating various waste streams to produce high-quality, eco-friendly paver blocks. Over the years, the research focus has expanded from conventional materials to recycled aggregates, permeable designs, and photocatalytic applications. This study identifies research gaps, such as the need for long-term performance assessment and life cycle analysis, and recommends future directions, including integrating paver blocks into urban planning and design strategies. The findings guide researchers and policymakers in the development of sustainable, resilient, and multifunctional paver block solutions.
