Mix temperature will be dependent on the grade of asphalt used in the mix. The less viscous the asphalt, the lower the temperatures should be. The more viscous the asphalt, the higher the temperature can be. During mix design temperatures are specified for proper mixing and for compaction. These are good targets with which to start a project.

The ia Department of Transportation (VDOT) specifications, standards, and test methods have been the standard in ia for more than 50 years. During that time VDOT has changed their nomenclature for asphalt mixes several times, typically following a major rewrite of their asphalt specifications and mix design criteria.
The Marshall mix design method can use any suitable method for estimating optimum asphalt content and usually relies on local procedures or experience. Sample Asphalt Binder Contents Based on the results of the optimum asphalt binder content estimate, samples are typically prepared at 0.5 percent by weight of mix increments, with at least two ...
