Road infrastructure, vital for a nation's socio-economic progress, has traditionally relied on resource and energy-intensive methods. The demand for sustainable solutions, particularly in urban areas, with greater resistance to increasing traffic loads, lower moisture sensitivity, and suitability for cold regions, is evident. Cold Mix Asphalt (CMA), benefiting from recent technological advancements, emerges as a promising solution. This paper examines the development of cold-mix pavement materials in the context of Canada's road networks. This literature review compares CMA to Hot Mix Asphalt (HMA) and Warm Mix Asphalt (WMA) in various aspects. While CMA offers advantages such as suitability for emergency repairs, ease of application, and cost-effectiveness, drawbacks include lower durability compared to HMA and the lack of internationally recognized standard tests, posing challenges in performance assessment, thus, decreasing predictive accuracy. Despite these drawbacks, CMA stands out for its energy-saving and environmentally friendly attributes, as it is mixed at considerably lower temperatures. This paper emphasizes the importance of further research into High-Performance CMA (HPCMA), especially considering ongoing environmental concerns. Recognizing both advantages and challenges, the review underscores the need for comprehensive understanding and continued research to develop resilient HPCMA pavements comparable to conventional HMA.
