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

Feb 02, Warm Mix Asphalt. Warm-mix asphalt is made similar to that of hot-mix asphalt, although it is 50 to 100 degrees Fahrenheit lower. The main advantage of hot-mix asphalt is the environment, as it uses less compacting exertion during construction and, as a result, releases less CO2. Warm-mix asphalt appears to be more costly but is a realistic

Jan 11, Warm mix asphalt is a mixture in which the liquid component of asphalt or bitumen is replaced by an application of warm aggregates. Warm mix asphalt reduces environmental damage, increases productivity, and lowers costs when compared to hot applications. Water utilization saves about in production cost over traditional paving

The major modifications recommended are reduction in initial compaction of test specimens, a specimen cure sequence and recompaction at the accepted 1400F test temperature. Since these modifications for use with solvent-free asphalt emulsion cold mixes1 the high mixing and compaction temperatures associated with the preparation of hot mix specimens is

In Virginia, most asphalt concrete (AC) is produced using specifications established by the Virginia Department of Transportation (VDOT). AC mixes are divided into several categories surface mixes, intermediate mixes, base mixes, and drainage layer mixes. Within each category, one or more actual mixes may be
