Asphalt Road Pavements to Address Climate Change Challenges—An Overview

Abstract

Climate change is already happening. It is one of the significant challenges that the planet has to face. Asphalt road pavements cover a large area of the Earth’s surface; consequently, climate change challenges can significantly affect their performance and serviceability. Thus, pavement solutions have been developed to address the problem. This paper aims to present an overview of those topics to increase awareness among transportation engineers and practitioners. First, the most significant aspects of road asphalt pavements’ materials, design and condition are presented. Second, the most relevant climate change challenges for asphalt pavements are described. Then, different pavement solutions are presented. This overview concludes that there are pavement solutions able to address climate change. These depend on local climate conditions and should be incorporated into the decision-making process in planning, design and maintenance.
