Compaction Aid and Warm Mix Asphalt (WMA) Additives. In order for pavements to last, they must be properly constructed. Achieving the required density has often been considered the single most important factor affecting the ultimate performance of any pavement.
Warm-Mix Usage Reaches New Heights. The latest NAPA/FHWA survey of asphalt producers' use of recycled materials and warm-mix asphalt find that nearly a quarter of all asphalt produced during the 2012 construction season was produced using warm-mix asphalt technologies.About Us · Submission Form · Contact Us · About WMA · Publications

Warm Mix Asphalt Technologies and Research. European countries are using technologies that appear to allow a reduction in the temperatures at which asphalt mixes are produced and placed. These technologies have been labeled Warm Mix Asphalt (WMA).
HOT MIX ASPHALT ADDITIVES. Liquid anti-stripping asphalt additives or adhesion promoters are chemicals added to asphalt to improve aggregate coating and increase the strength and frequency of chemical bonding between asphalt and aggregate.
Anova™ non-toxic, liquid warm mix additive is designed to significantly improve the quality and reliability of asphalt pavement compaction at an efficient dosage. Made from biobased chemistries, our warm mix additives provide economic value through lower plant costs due to …
Warm mix asphalt has an initial cost higher than traditional hot mix asphalt. On average, warm mix asphalt costs between $3 and $5 more per ton than hot mix asphalt because of the additives that need to be added. Warm mix asphalt uses less fuel and can be placed faster than hot mix asphalt.
The objectives of this study were to investigate the effects of two commercial warm-mix additives, a proprietary siloxane-based surfactant and oxidized polyethylene wax, on the quality and durability of a superior quality asphalt and two lesser quality asphalts.
Warm Mix Asphalt (WMA) is the generic term for a variety of technologies that allow producers of Hot Mix Asphalt (HMA) pavement material to lower temperatures at which the material is mixed and placed on the road. It is a proven a technology that can Reduce paving costs. Extend the paving season. Improve asphalt compaction.

Warm mix asphalt is one of the preferred alternatives for paving as it is more environmental friendly than the hot mix asphalt, but with virtually identical results. Increased haul distances from the plant to the site makes it difficult to pave with its reduced workability due to reduction in temperatures over haul time.
Based on seven sections of warm mix placed on Germany’s autobahns, warm mix performs as well or better than hot mix, Prowell said. The warm mix additives tested in Germany were Sasobit, Asphaltan B, Subit, and Aspha-min (zeolite). Sasobit and Asphaltan B are both wax-based additives, and Subit is a fatty acid amide. Minimal Concerns to Date

Asphalt industries consume large amounts of fuels and emit pollutant gases into the atmosphere. Warm mix asphalt is the most recognized way to minimize these negative impacts, which have given rise to numerous issues related to their performance and the materials used.
Summary The use of warm mix asphalt (WMA) instead of hot mix asphalt (HMA) is more environmentally friendly. Developed WMA technologies allow to reduce the mixing and compaction temperatures by 20-40°C. One of them is asphalt foaming technology which provides a foaming effect in mixing phase by use of water-containing additives such as zeolites.
use of additives. Warm Mix Asphalt (WMA) is an example of such additives which lowers the temperature of the asphalt mix between 30 to 120°F as compared to conventional HMA. A research study was conducted to evaluate additives Evotherm M1, …
