Effect of Aspha-Min Zeolite on the SBS Modified Asphalt-Filler Interaction
As a foaming agent in the preparation of foamed asphalt warm-mix mixtures,zeolite water released from zeolite and its residual zeolite minerals have different influences on asphalt-filler interaction.The effects of zeolite,zeolite minerals,and zeolite water on the rheological properties of SBS modified asphalt and its mastic were studied by rheological tests.It is found that the addition of zeolite or zeolite minerals to asphalt or mastic can increase the elasticity with the increase of its dosage,while zeolite water is on the opposite.On this basis,the effects of zeolite,zeolite minerals and zeolite water on the asphalt-filler interaction were studied by using the interaction evaluation indexes[η],Palierne-C-G*,and Luis Ibrarra-A-δ via rheological properties.It has been shown that the addition of zeolite or zeolite minerals to mastic can increase the asphalt-filler interaction with the increase of its dosage,while zeolite water is on the opposite.
