One of the factors contributing to the deterioration of asphalt and concrete pavements is the presence of soluble salts in the materials. In the first chapter of this book, a review of research conducted on the use of non-potable water in pavement compaction and its impact on the technical specifications of these layers, considering the existing technical requirements, is discussed.
The second chapter examines reports related to the damage caused by salt crystallization in various locations around the world. The third chapter delves into the theoretical basis of the mechanism of damage caused by salt crystallization. This includes discussions on various concepts such as crystallization pressure, efflorescence, evaporation, etc., and their effects on different types of salt behavior, the potential for pressure from hydration and thermal expansion, and the impact of mixing various salts.
In the fourth chapter, a brief overview of the signs and types of potential damage caused by salt crystallization, along with the factors influencing such damages, is presented. Furthermore, various suggestions for preventing damage and the necessary measures for repairing affected pavements are discussed.
