Table 3: Compactibility of WMA with zeolites. right compaction method is relevant in all further evaluation of WMA. The density and volumetric properties depend strongly on the compaction method and must be considered when applying the requirements of standards for the mix. At the moment, there are no recommendations with regard to WMA sample compaction. The zeolite addition did not prolong mixing times at the plants. Gradual zeolite water release allows the improvement of WMA workability, not only over production time, but also at the time of embedding the mix in the surface. The time from production until embedding constituting the WMA transport time is important in industrial production of WMA with zeolites. The temperature of WMA production and its transport time should be selected so that the temperature of mix at the spreading machine achieve assumed value, while taking note of atmospheric conditions. In each case, the schedule of production, storage, transport, and embedding should be planned carefully.
