Abstract: The article describes first Polish experiences in use of deep cold recycling technology with foamed bitumen, which was used for producing rehabilitated base courses on moderately trafficked roads. Design practices, testing methodologies and requirements for this technology are presented, based on the completed road sections with foamed bitumen cold bases that taken place in central Poland in the recent years. The obtained results are a proof that this technology is highly versatile in converting different materials into a high quality road base. The observed excellent five year performance of the roads constructed using this technology proves the effectiveness and validity of putting it into practice in the demanding local climatic conditions of Poland.
