Abstract EN
Warm mix asphalt (WMA) is mixed at temperatures ranging 20 – 50 °C lower than those in which called hot mix asphalt (HMA).
The use of synthetic zeolites as a warm mix asphalt additive has exhibited many additional advantages, such as a reduced susceptibility to permanent deformation.
However, there are also indications that the use of synthetic zeolites as a warm mix asphalt additive for some percentages increases the moisture sensitivity of pavements except for 5% there is a slightly improve.
The results of the study indicated that the selected percentages of synthetic zeolite to the warm asphalt differently effected on the mixture properties.
When the mixture properties were compared, it was observed that WMA with 3% of synthetic zeolite reduced the indirect tensile strength value, also the WMA mixture with 5 % of synthetic zeolite decreased the rut depth of the mixtures and slightly increased in the tensile strength ratio C lower than those in which called hot mix asphalt (HMA).
