摘要

Asphalt concrete has always been the foundation for constructing resilient and durable road infrastructures. The enhanced performance of asphalt concrete in recent years has facilitated the development of high modulus asphalt concrete (HMAC). The primary objective of this review is to provide insight into the current advanced asphalt technology, including material composition, mix design, and mechanical performance parameters; compare the asphalt technologies adopted by different countries; and discuss the innovations, challenges, and prospects shaping the future of asphalt technology. Besides exploring innovative ways of utilizing environmentally friendly materials and pavement technologies, this paper analyzes climate change and the urgent need to reduce carbon footprints. It also discusses the prospects of utilizing HMAC, including the opportunities and challenges in various infrastructure applications. The literature review revealed that HMAC offers a promising approach to improving asphalt pavement performance, reducing the base layer thickness of asphalt, and reducing costs, energy consumption, and environmental impact. Several countries are enthusiastic about utilizing HMAC due to its exceptional durability and performance compared to conventional asphalt concretes. The future directions for HMAC are emerging technologies and sustainable practices. This review summarizes the insights from recent research, industry developments, and technological innovations to provide a comprehensive perspective on high-performance asphalt concrete. This continuously evolving field of road construction is a valuable resource for researchers, practitioners, and policymakers.
