Warm mix asphalt (WMA) for rapid construction in airfield pavement [PDF]

Construction and Building Materials, 2020
Abstract Warm-mix asphalt (WMA) is commonly mixed and compacted 15°C to 30°C below that of conventional hot mix asphalt (HMA). The lower production temperature of WMA is expected to give an advantage of a lower cooling time of newly laid asphalt overlay before it can be opened to traffic during the nighttime airfield pavement construction.

Rheology of Crumb Rubber-Modified Warm Mix Asphalt (WMA). [PDF]

Polymers (Basel)
This study explores the impact of adding waste vehicular crumb rubber to the commercially available warm mix additives Sasobit® and Zycotherm® on modified asphalt binders’ physical and rheological properties. Various concentrations of crumb rubber (0%, 10%, 15%, and 20%) were introduced to asphalt binder samples with 2% and 4% Sasobit and 1.5% and 3 ...

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.

Evaluation of Resilient Modulus and Rutting for Warm Asphalt Mixtures: A Local Study in Iraq

Applied Sciences, 2022
Warm-Mix-Asphalt (WMA) allows aggregates to be coated with asphalt binder at a temperature lower than the Hot-Mix-Asphalt (HMA) temperatures by using additives that make the asphalt mixtures more workable and the asphalt binder viscosity reduced.

Laboratory Investigation of the Effect of Warm Mix Asphalt (WMA) Additives on the Properties of WMA Used in China [PDF]

Journal of Testing and Evaluation, 2014
Abstract To investigate and compare the influence of various commonly used warm mix asphalt (WMA) additives on the physical, mechanical, and performance properties of WMA, a series of laboratory testing programs such as air void, voids in mineral aggregate, freeze-thaw splitting, wheel tracking test, and bending beam tests were performed.
