Prior to the adoption of the Superpave mix design methodology, Marshall stability and flow testing was a simple index test that was widely used to quickly assess asphalt mix quality during both design and construction. In the decades since Superpave implementation, asphalt mixes have been designed using only volumetric methods; however, ideal volumetric proportioning is not necessarily indicative of mix quality. Research on the NCAT Pavement Test Track has validated the use of relatively simple balanced mix design (BMD) index tests that can be successfully used to screen mixes for cracking and rutting performance. Using these tests provides agencies and owners with confidence in asphalt mix quality; at the same time facilitating innovation by mix producers that optimizes both sustainability and cost. A simplified BMD specification was developed for Alabama county purchase order mix that can easily be implemented for small agency work and on commercial projects where good performance is essential. This workshop was developed to equip attendees to utilize the simplified BMD specification. The target audience is county engineers, city engineers, consultants, contractors, and developers who wish to improve asphalt pavement quality and incentivize innovation.
