The road pavement structure (apart from having the required load capacity) should be water and frost resistant. This is important for pavements produced with the cold recycling technology. Foamed bitumen and, alternatively, bitumen emulsion were used for the resistance tests of the pavements. The bitumen binder content in the recycled material was 2.0%, 2.5% and 3.0%. The tests (stability against deformation, Marshall stiffness and indirect tensile strength (ITS)) showed that use of foamed bitumen is more advantageous than bitumen emulsion. That is in terms of mechanical properties of pavement. The measurements of resistance due to water and frost (according to AASHTO T283 method) and resistance to low temperature cracking (according to the PANK 4302 method) confirmed that pavement produced with the cold recycling technology is resistant to these climatic factors. The tests also showed that pavement produced with foamed bitumen is more resistant than pavement with bitumen emulsion. It is suggested, that general water resistance criterion (tensile strength retained (TRS)) of such pavement should be broadened to include e.g. the AASHTO T283 method.
