春风塔河沥青抗老化性能研究

Study on the Anti-aging Performance of Chunfeng-tahe Asphalt

硬春风塔河沥青是中国石化结合春风原油与塔河原油的资源和性能优势研发生产,产品指标满足交通部A级标准。通过室内老化模拟试验,分析老化后沥青及混合料性能指标,证明其具有良好的抗老化性能,适用于路面材料要求较高的路面结构层。

SINOPEC successfully produced Chunfeng - tahe asphalt basing on the resource and perform-ance advantages of Chunfeng crude oil and Tahe crude oil, this product ’ s indicators satisfied the A grade standard of Ministry of Transport. In this article, through simulation test of aging, the performance of aged as-phalt and aged asphalt mixtures are analysis. The results prove that Chunfeng - tahe asphalt has good anti - aging performance, is suitable for pavement structure layer which require better road surface material.
