用中间-石蜡基新疆混合原油的丙烷脱油沥青与富芳贫蜡改性剂调合,可生产出符合国家标准GB/T15180-94要求的各种牌号重交通道路沥青。沥青的路用性能研究表明,常用的90号调合沥青与新加坡90号重交通道路沥青相当。用90号调合沥青在西安铺筑了试验路,通过1年多的使用观测,未发现沉陷、裂纹、拥包、车辙等现象,路况良好,回弹模量等6项路用性能指标也全部符合设计和规范要求。实践表明,研制的沥青完全可以用于高等级公路建设。
With the middle - Paraffin-based Xinjiang mixed crude oil propane de-bitumen asphalt blending with rich arsenic-poor wax modifier to produce a variety of national standards GB / T15180-94 requirements of heavy traffic road asphalt. Asphalt road performance studies have shown that the commonly used No. 90 asphalt blend with Singapore No. 90 heavy traffic asphalt equivalent. The test road was paved with No. 90 asphalt blended with asphalt in Xi’an. After more than one year of observation, no signs of subsidence, cracks, embracing, rutting, road conditions and rebound modulus were found All meet the design and specification requirements. Practice shows that the asphalt developed can be used for high-grade highway construction.
