Popis:	The paper presents research in the field of utilizing materials recycled from concrete pavements through crushing and re-incorporating them in road embankments and improved subgrade layers. Crushed concrete rubble is an alternative source of aggregates, replacing natural aggregates. Recycled concrete aggregate was tested with regard to the current national requirements. It was proven that recycled concrete aggregate is a suitable material for incorporation into new unbound and cement-bound layers of the improved subgrade. The problem of utilization recycled concrete aggregate in road embankments is also addressed in the paper. Limitations in the use of recycled concrete aggregate are also shown in the paper.
