Visco-elastic characterisation of zeolite modified asphalt ...

A recent warm mix asphalt technology uses zeolite powders as an additive to reduce production temperature and improve workability. With an increase in temperature, water is released from the zeolite crystalline structure and vaporised into bubbles within the binder, and thus gas, fluid, and solid phases simultaneously exist in the modified binders.
