摘要
粘度是表征沥青稠度的一个重要指标。通过论述石油沥青粘度测定法(真空毛细管法)中毛细管的选择、温度、真空度、取样量等对试验结果的影响及试验过程中的其它注意事项,表明了在测定石油沥青的60℃动力粘度时,必须严格按照试验方法的要求进行测定,以保证试验结果的准确性。
One of the primary index tokenning the consistency of asph viscosity. Effect factors on determination viscosity of petroleum asphalt consequence have been discussed. Including selected capillary, temperature, vacuums and inaccurate operation. The result indicated that trier should determinate strict according to test method for ensure accuracy in the course of determination.
