摘要
沥青与沥青混合料作为一种非常重要的土工材料 ,被广泛应用于道路路面和建筑防水 ,有关研究也在世界各地展开。然而关于这两种材料的流变特性之间的联系在目前来说还是个未知数。通过比较沥青与沥青混合料的均质性、颗粒性 ,粘弹性及其流变模型 ,来分析这两种材料在力学方面的相似性和差异性。研究表明 ,沥青和沥青混合料具有相同的粘弹性性质 。
Bitumen and bituminous mix, as a very important kind of geomaterial,are generally applied to the road pavement and some waterproofness constructions,many investigations about them have been carried out all over the world, however it seems that the relation of mechanical behaviour between these two considered materials is yet unknown at the present.This paper analysed and defined some mechanical similarity and differencity between bitumen and bituminous mix by a comparison study with considering their homogeneous,granular and viscoelastic characteristics, and their rheological model.The results show that the bitumen and bituminous mix have a same viscoelastic behaviour, the only difference between them is the structural composition of materials.
