High Modulus Asphalts (HMAs) have appeared as a promising solution for enhancing the longevity and performance of road infrastructure in various countries. This review article provides an exhaustive analysis of the application, methodologies, and specifications associated with HMA of China, EME of France, and Superpave of the United States of America in the context of road infrastructure. The study delves into the distinguishing characteristics of HMA, EME, and Superpave, emphasizing their remarkable traits and benefits. Also, it discusses the methodologies utilized in each country for the design, exhibition, and quality control of asphalts used in road infrastructures. A diminishing review of the specifications and standards governing these technologies is also provided, alleviating light on the rigorous criteria set forth by each country's regulatory authorities. In addition to the technological characteristics, the article also discusses case studies and real-world examples from China, France, and the USA, illustrating how these high-modulus asphalt technologies have been successfully implemented to enhance the durability and performance of roads. • HMACs reduce layer thickness by 30–35%, improving load distribution and durability. • China uses "strong base, thin surface" for longer pavement life. • In France, EME2 focuses on durability with advanced binders. • Analogized to China and France, the USA embraces high-viscosity modified asphalt for high-modulus designs. • Polymer-modified asphalts improve rut and crack resistance.
