Title	QC/QA testing differences between hot mix asphalt (HMA) and warm mix asphalt (WMA), 2010

Publisher	Oklahoma Department of Transportation
Publication Date	2010-10-31
Publication Type	Research Report/Study
Purpose	The following report summarizes the work accomplished to date on a two-year study on QC/QA differences between warm mix asphalt (WMA) and conventional hot-mix asphalt(HMA). WMA represents a group of technologies which allow a reduction in the temperatures at which asphalt mixtures are produced and placed on the road. These technologies tend to reduce the viscosity of the asphalt cement allowing coating at lower temperatures. Reductions of 35 to 100oF have been reported. Such drastic reductions have the obvious benefits of cutting fuel consumption and decreasing the production of greenhouse gases. In addition, potential engineering benefits include better compaction on the road, the ability to haul paving mix for longer distances, increased RAP percentages, and the ability to pave at lower temperatures.; The objectives of this study are to develop testing protocols for the different WMA additives for mix design and QC/QA procedures. For mix design, testing protocols need to be developed for rut testing and moisture sensitivity testing. For QC/QA, protocols need to be developed for lab-molded void properties and asphalt content. To meet the objectives, equivalent compaction temperatures and/or compactive efforts need to be established for WMA additives.
