Efficiency of Use of Slag waste in Road Construction
Journal Title: Экономика строительства и городского хозяйства - Year 2017, Vol 13, Issue 1
Abstract
The necessity of lowering the costs for the construction of highways has been proved. The technical and economic parameters of the three variants of pavement construction are compared, using: a) ash-and-slag waste mixtures, b) sand and c) gravel-sand mixture. The calculation found that from a technical point of view, it is possible to implement all the considered options for the construction of the roadway, regardless of technology and construction costs. It is determined that the greatest savings are achieved when using ash-and-slag waste mixtures, in comparison with other materials. Construction, with the use of dump ash and slag mixtures, is carried out without loss of strength and structural stability at all stages of construction, thereby achieving the stated goal of the study. The condition of strength was traced by calculating the design of pavement for elastic deflection.
