Effects of Warm Mix Asphalt (WMA) Additives on the Properties of WMA Mixtures
Applied Mechanics and Materials, 2013The objective of this research was to investigate the influence of Warm Mix Asphalt (WMA) additives on asphalt mixture properties through the laboratory testing programs such as air voids, tensile strength ratio (TSR), dynamic stability, and low temperature bending failure strain tests. The experimental design included the use of three WMA additives of

Use of reclaimed asphalt pavement (RAP) in warm mix asphalt (WMA) pavements: a review
Innovative Infrastructure Solutions, 2017The limit in the use of reclaimed asphalt pavement material (RAP) proportion is restricted due to stiffness and workability issues related to RAP. This problem is addressed with the help of warm mix asphalt (WMA) which increases the proportion of RAP used by producing mixes having same/better properties viz., better workability, reduced viscosity than ...

Hot mix asphalt (HMA) is extensively used worldwide for the construction of bituminous pavement. However, the need to make the pavement industry more ecological has led to the evolution of the warm mix asphalt (WMA) concept. Mixing and compaction temperatures for WMA are lower than the conventional HMA production temperatures.

Materials and Structures, 2020
Studies show that warm mix asphalt (WMA) technology is a practical solution against the high production temperature of rubberized-asphalt (RA) mixtures. RA mixture containing WMA additive is considered as an eco-friendly technology contributing to noise reduction and performance optimization of asphalt mixtures. This study aims to introduce two organic

Wind Speed Effect on the Time Available for Compaction of Warm Mix Asphalt (WMA)
Key Engineering Materials, 2020High demand for new asphalt pavements often requires that paving is to be done in an unfavourable condition such as low air temperatures, high wind speeds, and night construction that will affect the Time Available for Compaction (TAC). In local practice, the asphalt paving compaction control mechanisms quoted from the locally used specifications are ...
