摘要

摘要: 为了准确评价天然沥青改性沥青与集料的粘附性能, 采用座滴法测定了3种液体在天然沥青改性沥青试样表面的接触角, 基于表面物理化学理论, 确定了室温条件下沥青表面自由能极性分量和色散分量的测定方法, 计算了基质沥青和不同掺量天然沥青改性沥青的表面自由能。结合水煮法试验结果, 分析了沥青结合料表面自由能与沥青-集料粘附性等级的关系。试验结果表明: 70^#A级基质沥青的表面自由能为10.60 mJ·m^-2, 而8%掺量天然沥青改性沥青表面自由能增加到18.60 mJ·m^-2, 天然沥青的掺加明显提高了天然沥青改性沥青的表面自由能; 采用接触角方法得到的沥青结合料表面自由能和沥青-集料的粘附性能具有较好的相关性; 天然沥青含有氧、硫、氮等多种极性较强的官能团, 较高的沥青质含量及网状结构能够吸附基质沥青中的饱和分和芳香分等轻质成分, 两方面的共同作用提高了天然沥青改性沥青的表面自由能。

Abstract: In order to accurately evaluate the adhesion of asphalt modified with natural asphalt and aggregate, the contact angles of three liquids on the sample surface of asphalt modified with natural asphalt were measured based on sessile drop method. According to the theory of surface physical chemistry, the measuring method of polar component and dispersion component for asphalt surface free energy under the condition of room temperature was determined. The surface free energies of base asphalt and asphalts modified with different dosages of natural asphalt were calculated. The relationship between asphalt surface free energy and asphalt-aggregate adhesion grade was analyzed based on the test result by using water-boiling method. Test result shows that the surface free energies of 70^# grade A base asphalt and asphalt modified with 8% natural asphalt are 10.60, 18.60 mJ·m^-2 respectively, so the surface free energy of asphalt modified with natural asphalt increases distinctly with the addition of natural asphalt. There is a good correlation between asphalt-aggregate adhesion and the surface free energy of asphalt calculated by contact angle method. The natural asphalt contains higher polar functional groups such as O, S and N etc. High contents of asphaltene and net structure can absorb the light components of base asphalt such as saturates, aromatics. The increase of surface free energy for asphalt modified with natural asphalt is attributed to the polar functional groups and the absorbing functions.
