Recent developments in the application of chemical approaches to rubberized asphalt

摘要: Abstract Although rubberized asphalt has more than a 50-year history, it not been widely adopted due to difficulties with its processability, unstable properties and high initial cost. Chemical approaches, including chemical characterization the addition of additives asphalt, are useful tools promote applications this technology. techniques such as infrared spectroscopy, thermogravimetric analysis, gel permeation chromatography, sol-gel analysis used analyze composition asphalt. The development for is described in terms degradation rubber stabilization evolution evaluated correlated dry wet processing, indoor outdoor aging. Following this, performance realized by modification different also discussed. categorized into polymers, inorganic filler, plasticizer others. Finally, methods that combine several types can be produce stable an environmentally friendly manner described.
