一、前言交通量的不断增长,有必要提高道路工程的质量。为此,出现改善铺筑桥面、表面处治、薄层路面以及防滑层所用结合料品质的趋势,措施之一就是研究应用聚合物改性沥青。现在,已按照下述目的来研究改善这类结合料的品质。1.充分提高结合料在路面达到最高温度时的粘度(稠度),以防止沥青路面产生塑性变形;2.提高结合料在低温下的柔韧性和弹性,以避免路面形成裂缝及石屑散失;
First, the foreword The constant growth of traffic, it is necessary to improve the quality of road projects. Therefore, there is a tendency to improve the quality of the binder used in paving the bridge deck, surface treatment, thin pavement and non-slip layer. One of the measures is to study the application of polymer modified asphalt. Now, in accordance with the following purposes to study to improve the quality of such binders. 1. Fully improve the viscosity of the binder when the pavement reaches the highest temperature (consistency) to prevent the plastic deformation of the asphalt pavement; 2. To improve the flexibility and elasticity of the binder at low temperatures to prevent the formation of cracks in the pavement and stone chips;
