Pavement Materials for Adapting Climate Change

Abstract

Pavement materials that minimize water infiltration are essential in addressing performance issues caused by temperature and moisture fluctuations, which often lead to cracking, rutting and other forms of degradation. To combat these challenges, innovative materials and climate-responsive pavement designs have been developed, incorporating recycling methods and region-specific mix designs to withstand climatic stresses and reduce maintenance costs. Porous pavements are particularly effective in managing climate-related challenges. Engineered to allow water infiltration, they reduce surface runoff, mitigate urban flooding and enhance road safety. In high-rainfall areas, their permeable structure lowers risks such as hydroplaning and surface water accumulation. In colder regions, they minimize freeze-thaw damage by facilitating water drainage which helps prevent ice formation and reduces pavement cracking. The inclusion of polymers and fibers in these materials enhances their strength, durability and lifespan. Additionally, porous pavements contribute to urban cooling through evaporative processes, mitigating the urban heat island effect. They also support groundwater recharge, aligning with sustainable water management practices. By decreasing maintenance needs and environmental impact, porous pavements play a vital role in creating climate-resilient infrastructure that promotes urban safety and sustainability while conserving resources.
