Rutting and moisture-induced damage potential of foamed warm mix asphalt (WMA) containing RAP [PDF]

Innovative Infrastructure Solutions, 2021
AbstractDespite significant economic and environmental benefits, performance of warm mix asphalt (WMA) containing reclaimed asphalt pavement (RAP) remains a matter of concern. Among the current WMA technologies, the plant foaming technique (called “foamed WMA” in this study) has gained the most attention, since it eliminates the need for chemical ...

Coupled effects of warm mix asphalt (WMA) additives and rheological modifiers on the properties of asphalt binders

Cleaner Engineering and Technology, 2020
Asphalt pavements, as an essential element affecting the economic vitality of the countries, are widely used to construct the highways and expressways. Severe climate conditions and traffic loads can influence the service life of asphalt pavements and lead to distresses such as thermal cracking and rutting.
