Abstract

A lot of research centres in the world deal with developing the reuse of waste technology. The processed waste is applied in many industries, especially in the infrastructure construction. The European standards allow to apply recycled materials in implementation of buildings and the road engineering. In most cases, the detailed classifications for recycled aggregates are the subject of domestic standards, in which this topic is studied and developed deeply (Germany, Austria). In Poland, at the stage of applying the recycled aggregate, contractors are forced to rely on German or Austrian guidelines. In many cases, the application of the recycled materials is based on the contractors’ experience or intuition. That is why each additional development expansion of the knowledge on the recycled aggregates is added value and is very helpful for designers and contractors. The paper presents the comparison of mechanical resistance to fragmentation in a Los Angeles abrasion machine of selected crushed-stone and recycled aggregates (crushed concrete rubble) from demolished road structures.
