Abstract
Embodiments provide slurries of water and zeolite. These slurries have beneficial properties when mixed with asphalt. These beneficial properties may include extension of the asphalt as well as a decrease in the temperature used to process the cement. In some embodiments additional additives are included, such as anti-strip amines. Methods of making and using the slurries, as well as cement mixtures incorporating the slurries are also included herein.
