为了研究温拌沥青胶浆流变性能,通过动态剪切流变试验,研究了投料顺序、温拌剂类型、温拌剂掺量、沥青类型和粉胶比等因素对温拌沥青胶浆流变性能的影响规律。研究结果表明:矿粉与温拌剂的添加顺序对温拌沥青胶浆的流变性能基本没有影响;Sasobit降低了温拌沥青胶浆的流变性能,3G提高了其流变性能;随着温拌剂掺量的增大,沥青粘度的增加和粉胶比的增大,温拌沥青胶浆的流变性能显著降低。
In order to study the rbeological properties of harm mix asphalt mortar, based on the results of dynamic shear rheological test, the effects of mixing procedure, warm mix agent type warm mix agent dosage, asphalt type and ratio of filler were analyzed on the theological proper ties of it. The research shows that mixing procedure of filler and warm mix agent is has almost no influence on the theological properties. Sasobit reduces the rheological properties of warm mix as phalt mortar, but 3G improves the theological properties; and the rheological properties of warm mix asphalt mortar decreases with warm mix agent dosage, asphalt viscosity and ratio of filler to asphalt increases. 4 tabs, 5 figs, 12 refs.
