The objectives of this project were to (1) establish relationships among engineering properties of WMA binders and mixes and the field performance of pavements constructed with WMA technologies, (2) determine relative measures of performance between WMA and conventional HMA pavements, (3) compare production and laydown practices between WMA and HMA pavements (including necessary plant adjustments to optimize plant operations when producing WMA), and (4) provide relative emissions measurement of WMA technologies as compared to conventional HMA technologies.
