Achieving Volumetrics and HMA Compactibility. The Bailey method was originally developed by Robert D. Bailey of the Illinois Department of Transportation in the early 1980s. It is a practical tool that has been successfully utilized for developing and analyzing hot asphalt mixes in the lab and field.
Improving Hot Mix Asphalt Performance with SUPERPAVE
Improving Hot Mix Asphalt Performance with SUPERPAVE. A Driving Force In Asphalt . SUPERPAVE Update for Intevep April 8, 2002
Superpave Mix Design
Air voids (V a), sometimes expressed as voids in the total mix (VTM) Voids in the mineral aggregate (VMA) Voids filled with asphalt (VFA) Generally, these values must meet local or State criteria. VMA and VFA must meet the values specified in Table 8.
Fix your mix
When VMA is lowered, you lower the asphalt binder content for a given air void level (typically 4.0 percent for Superpave mix design). And when you lower the asphalt content, the mix becomes more economical but also less durable. To understand proper VMA, we can go back to the 1990s during the development of Superpave. A critical component of ...
Performance Evaluation of Stone Mastic Asphalt and Hot Mix
Environmental and economic considerations have encouraged civil engineers to find ways to reuse recycled materials in new constructions. The current paper presents an experimental research on the possibility of utilizing recycled concrete aggregates (RCA) in stone mastic asphalt (SMA) and hot mix asphalt (HMA) mixtures. Three categories of RCA in various percentages were mixed with virgin ...
