Moisture susceptibility of warm mix asphalt concrete containing synthetic zeolite

The primary objective of this study was to perform a laboratory testing to determine the moisture sensitivity of an asphalt concrete produced in warm mix asphalt technology (WMA) with the addition of the synthetic zeolite. The usage of this technology may cause potential difficulties like the insufficient mixture compaction or undesirable impact of some WMA additives. One of the design assumptions was the potential adhesion problem. That is why the addition of hydrated lime was also evaluated as anti-stripping agent to WMA with the zeolite.
