Abstrakt: Low-temperature stripping, medium-temperature fatigue cracking and high-temperature rutting are prominent premature failures in flexible pavements. The premature failures and the pavement durability aspects can be prevented with the use of modified binders, admixtures, inclusion of Recycled Asphalt Pavement (RAP), innovative mix design practices, which shall be achieved by aggregate packing characteristics and a few other technologies are also in place. Warm Mix Asphalt (WMA) and Cold Mix Asphalt technologies are being extensively used as an alternative for conventional Hot Mix Asphalt (HMA) technology, so as to make the construction process less energy intensive, lowering the carbon emissions and thereby ensuring the sustainability.
