Abstract The paper summarizes past experience in the use of reclaimed material in road construction layers according to various technologies applied in road construction. The recycling of asphalt pavements is a standard widely applied and established in road practice for many years. There is strong interest to increase the use of recycled materials in asphalt pavements for cost and environmental reasons. The paper defines the strengths and weaknesses of individual technologies and recommends where and when the use of R-material is appropriate, economically sound and technically justified. The production of new asphalt mixes with more reclaimed material is limited by more factors in the Czech Republic. They include the regulation of the quantity of reclaimed material in the standards and technical regulations. The machine equipment of contractors for recycling is not always sufficient either.
