Interpreting the effectiveness of antioxidants to increase the resilience of asphalt binders: A global interlaboratory study

The design and use of antioxidant additives to reduce or slow down the aging of asphalt binders can bring about tremendous benefits to the asphalt industry. Despite many isolated and scattered research efforts showing mixed results, the application of this science to engineering-based solutions has been limited due to variability in results and...

摩擦型轨枕道床的横向阻力研究

The Sichuan−Tibet railway is built under some difficult situations, including limited ballast bed profile, frequent earthquakes and large diurnal temperature variation. These difficulties cause insufficient lateral resistance of ballasted track, which is an urgent problem for the stability and resilience of the continuously welded rail (CWR)....
