Laboratory Simulation of Warm Mix Asphalt (WMA) Binder Aging Characteristics

Airfield and Highway Pavements, 2008
As warm asphalt has been gaining increasing popularity in the recent years, there are still several characteristics about warm asphalt that are unknown. While several studies have been conducted to study the performance of warm asphalt mixtures, aging characteristics of warm asphalt binders are not known in great detail as the technology is relatively ...

Warm Mix Asphalt (WMA) technologies: Benefits and drawbacks—a literature review

2016
Use of Warm Mix Asphalt (WMA) technologies is known as an effective method to reducing the energy consumption and emissions associated with conventional Hot Mix Asphalt (HMA) production. WMA technologies show significant benefits, such as extended window of paving season, attaining better compaction and providing longer haul distances.

Improving the fracture properties of asphalt pavements made with warm mix asphalt (WMA) using nano-molybdenum disulfide particles (NMDSP) under shear and tear deformations

International Journal of Pavement Engineering
Nano-molybdenum disulfide particles (NMDSP) have been able to improve the mode I fracture features of flexible pavements. However, the fracture performance of asphalt pavement under modes II and III is a research gap in this field. To cover the study gap

Life Cycle Assessment of Road Surface Paving with Warm Mix Asphalt (WMA) Replacing Hot Mix Asphalt (HMA)

2010 International Conference on E-Product E-Service and E-Entertainment, 2010
Based on a testing road construction project, where warm mix asphalt (WMA) replaced Hot Mix Asphalt (HMA) to be used on road surface paving, investigation was carried out to collect data on energy consumption and air emissions for all the steps including production of raw materials (HMA and WMA), transportation, paving and road surface rolling.

Evaluation of Warm Mix Asphalt (WMA) Technologies for Use in Airport Pavements

2020
Federal Aviation Administration (FAA) currently does not allow use of warm mix asphalt (WMA) on Airport Improvement Program (AIP) funded airport runway and taxiway pavement projects due to the lack of pavement performance data under heavy aircraft loads on WMA.

Binder and Mixture Testing to Assess Rutting Performance of Warm Mix Asphalt (WMA)

Green Streets, Highways, and Development 2013, 2013
Warm mix asphalt (WMA) technology is steadily gaining popularity due to the environmental, energy, and cost savings it offers as a sustainable alternative to conventional hot mix asphalt (HMA). However, adoption of WMA for commercial and military airfield pavements has been slow due to lack of documented good performance on airfields and concerns about
