Review of laboratory studies on performance of cold max asphalt using different additives
In the current study, the focus was made on upgrading or modifying the cold mix asphalt (CMA) to a stage where the mechanical properties of CMA are comparable to traditional hot mix asphalt (HMA). Additives like cement and/or lime or waste materials (by-products) could be used within the mixtures to improve the mechanical properties, like indirect tensile stiffness modulus, resistance to permanent deformation, creep stiffness. Cold mix asphalt (CMA) with comparable engineering properties to hot-mix asphalt (HMA) is a breakthrough in laying of asphalt, particularly because these require no heat within the manufacturing and, the rutting and structural resistance to distress that occurs in road pavement and life span of pavements can indeed be enhanced. Many research projects have seen major developments in the hot laying process. The key goal is to create and refine a high-performance CMA mixture for use as a surface track that can be used in any scenario instead of hot mix asphalt (HMA). Because of these changes mix technology. Cold mix technology lags behind in both the fields of science and implementation, which is very evident in India. It is the main justification that underlies the option of the said CMA as current research area. In fact, this also provides benefits for the environment and economic benefits as compared to HMA.
