摘要：

The paper presents the results from the fatigue tests of recycled bases containing foamed bitumen and bitumen emulsion. The amount of bitumen used in both cases was 3% and 5%. For the production of the bitumen emulsion and foamed bitumen, 70/100 pen bitumen was used. Portland cement I 32,5R was applied as a binder. The binder comprised 3% of the mineral composition of the recycled base layer. Fatigue tests were performed in compliance with the requirements of enclosure E of PN-EN 12697-24 at a constant normal stress of 250kPa, 375kPa and 500kPa. The results were used to compare the effects of the binder type applied to the recycled base and determine the service life in terms of the stress applied. (C) 2016 The Authors.
