Bituminous binders constitute 4-7% of the flexible pavements by weight play an important role on structural and functional performance pavements. Traditional hot mix asphalt (HMA) production is done at 150-190 °C that results high-energy usage, smoke odor emission therefore significant cost loss environmental damage. Increasing awareness has questioned whether HMA can be produced lower temperat...

Utilizing polymers with asphalt mixtures is one solution to improving the performance of mixtures. Warm mixed (WMA) technology has begun be widely used; however, hot (HMA) most common paving procedure worldwide. HMA some side effects, such as increasing emissions exhaust gases, which lead environmental pollution and air energy consumption. Thus, utilizing WMA would help improve mixture performa...

This investigation is centered around the application of warm mix asphalt (WMA) technologies to address workability concerns linked rubberized binders. The primary aim incorporating crumb rubber (CR) and WMA additives establish a robust paving method that fosters energy conservation, efficient waste management, noise reduction, improved overall performance. current study aims comprehensively ch...

The primary objective of this research is to evaluate the feasibility of several WMA mixtures as potential asphalt paving mixtures for Nebraska pavements. To that end, three well-known WMA additives (i.e., Sasobit, Evotherm, and Advera synthetic zeolite) were evaluated. For a more realistic evaluation of the WMA approaches, trial pavement sections of the WMA mixtures and their HMA counterparts ...

in this study, different contents of nano-silica, 2 wt.%, 4 wt.% and 6 wt.%, have been added to bitumen tomodify the physical, mechanical and rheological properties of warm mix asphalt (wma). wma iscontaining 2 wt.% of sasobit (mixture of long-chain hydrocarbons). various quality control tests have beencarried out to characterize the modified bitumen and wma. the rheological investigations show...
