摘要:

沸石作为制备泡沫沥青温拌混合料的发泡剂，其释放的沸石水和残留的沸石矿物对沥青-填料交互作用有着不同影响.通过流变学试验，研究了沸石、沸石矿物和沸石水对SBS改性沥青及其胶浆流变特性的影响.试验发现，在沥青或胶浆中添加沸石或沸石矿物可使其弹性增大，且随其掺量的增加而增大，沸石水则与之相反.进一步，利用基于流变特性的交互作用评价指标［η］、Palierne-C-G^*和Luis Ibrarra-A-δ，研究了沸石、沸石矿物和沸石水对SBS改性沥青-填料交互作用的影响.研究表明，胶浆中添加沸石或沸石矿物可使沥青-填料交互作用增大，且随其掺量的增加而增大，沸石水则与之相反.

Abstract:

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.
