This paper describes different types of concrete retaining walls and reinforced concrete retaining walls that are applied on roads. At the beginning, the retaining structures, their application in construction, and the loads that affect them are defined. In addition, retaining walls are described as a type of retaining structure that will be elaborated in more detail in this paper. Their various shapes and construction materials are briefly listed. After the introductory part, gravity retaining walls and their role on roads are described in more detail. These include concrete retaining walls and reinforced concrete retaining walls which are the main topic of this paper. The types that are most often used and constructed are listed for each of them in separate chapters, and their design, construction and drainage are described in detail. In the chapter related to concrete gravity retaining walls, prefabricated concrete walls made of preassembled elements are additionally described, whereas monolithic and prefabricated constructions are specially elaborated in the chapter related to reinforced concrete retaining walls. After the description of each type of wall, examples of machines used in different phases of construction both in concrete retaining walls and reinforced concrete retaining walls are given in the chapter dealing with mechanization in the construction of retaining walls, which was explained in more detail in previous chapters. Finally, an overview of the advantages and disadvantages of these types of walls is given, based on which a conclusion is made on which type of retaining wall is more cost-efficient and easier to construct.
