Abstract

Roller concrete is a type of concrete with slump is almost zero. Concrete concrete is a concave concrete roller whose resistance to its formation is similar to that of poured soil. The amount of moisture should be adjusted in such a way that, while providing the mixing conditions and the density of the concrete, the cement paste is uniformly spread in concrete and the concrete is subjected to the weight of the roller. Following the successful use of roller concrete in dam construction, the features and benefits of this type of concrete, including the ability to obtain high resistance at low ages and the need for arms, molding and payment, which facilitates and accelerates the implementation of the work, The use of this type of concrete in the pavement was encouraged. The use of commonly used equipment for the implementation of asphalt pavements to implement roller concrete concretes along with lower maintenance costs and longer shelf life has been instrumental in expanding the use of this type of concrete as pavement pavement. In our country, due to the increasing capacity of cement production to meet the needs of domestic civil engineering projects and the demand for export markets, the expansion of the use of concrete procedures on the roads as a practical way to create a sustainable consumption market for a part of the production of cement is posing. . In this paper, some laboratory experiments and achievements in the use of roller concrete as a pavement on the inner streets of the refinery, including the design of mixed designs using native materials and part of the stone waste materials, measures to improve the production line of materials Stone and Concrete Plant Factory To comply with the requirements for the construction and carrying of concrete rollers, considerations about the operation of conventional machinery for road construction for the implementation of roller concrete and the processing and maintenance of roller concrete in hot weather are detailed.
