摘要
根据薄膜烘箱试验的氧化历程建立了一种能评价和预测用氧化法生产 70号沥青时产品膜后性能的试验方法 ,经过实验室和工业的验证 :该种薄膜氧化法用来模拟和预测浅度氧化生产 70号沥青时产品的软化点、膜后低温延度和针入度比具有较好的准确性 ,这一特点在指导 A原油生产 1号
Based on the oxidation course of 'thin film oven test', we have established a test method of evaluating and predicting the properties of asphalt AH-70 after TFOT, which is obtained by blowing oxidation. The evidence from laboratory and processing unit supports that the method works well on simulating and forecasting softening point, low-temperature ductility after TFOT and penetration of oxidized asphalt AH-70, which is benefit to the production of asphalt No 1 AH-70 in processing unit.
