This paper presents a critical review and verification of the material characteristics of cement-modified material. The review delves into the key constituents of cement-treated aggregate material, including cement types, aggregate selection, and water-cement ratios, highlighting their influence on the final properties of the cement treated base and subbase layer. Moreover, the study examines the mechanical and durability characteristics of cement treated base (CTB) such as unconfined compressive strength (UCS), elastic modulus, poisons ratio, durability and fatigue characteristics, emphasizing the importance of material properties for long-term performance. Material characteristics paramount to the construction mechanism and dynamic behaviour are also discussed. An Overview of Continuum Damage Mechanics (CDM) and its applications in modeling material damage and fatigue characteristics in presented in this study. It emphasizes the significance of using a damage variable (D) to represent the severity of material damage, discusses relevant equations and models, and references previous research in the field. Construction techniques, quality control, and best practices for CTB installation are explored, with a focus on achieving uniform compaction and moisture content to ensure optimal strength and stability. Additionally, the environmental aspects of CTB are discussed, demonstrating its sustainability through the efficient use of local materials and reduced maintenance needs. •The UCS test is simple but can't accurately simulate material field behaviour.•UCS value is affected by cement content, aggregate type, compaction, and curing time.•The dynamic modulus of cemented material is often higher than the static modulus.•Strength and durability hinge on quality, testing, chemical factor and cement content.
