Property Characterization of Anti-Aging Additives and Hindawi
Commonly used anti-ultraviolet aging modifiers mainly include carbon black, nanomaterials, intercalation materials and ultraviolet light absorbers, and so on, The dispersibility of UV-resistant additives in asphalt binder was evaluated by using a fluorescence microscope. Then, the aging resistance of additives and their effects on virgin asphalt binder were qualitatively evaluated by calculating rheological parameters. The new aging-resistant index and impact index were defined.Evaluation on Feasibility of Carbon Black and Hindered Amine

Microwave Heating as an Innovative Road Maintenance Technology: Aging
The microwave heating/healing technique is regarded as a green maintenance approach for asphalt pavements thanks to its promising environmental and economic benefits. However, the main concern about this technology is represented by the possible aging effect generated on bituminous binders. Currently, there is a significant Instead the construction industry and its clients must start embracing technologies and designs which reduce the carbon footprint of roads and highway maintenance. When ministers announced 2030 as the end date for the sale of new petrol and diesel fuelled cars and vans, they said the move would have the same impact on Debate Building and maintaining low carbon roads

Antiaging agents: safe interventions to slow aging and healthy life
Human longevity has increased dramatically during the past century. More than 20% of the 9 billion population of the world will exceed the age of 60 in 2050. Since the last three decades, some interventions and many preclinical studies have been found to show slowing aging and increasing the healthy lifespan of organisms from yeast, flies, Trials are also underway of ‘anti-ageing’ bitumens, which seek to extend the longer life benefits of PMBs and thus reduce whole-life carbon footprints. In addition to materials innovation and enhancements, our sector is working hard to cut carbon throughout the road construction and maintenance supply chain.Low carbon approaches to road maintenance LocalGov
