Sep 15, 2017  The model estimated 24% more alligator cracking for the sandstone mix (VMA = 9.2%) compared with the coarse limestone mix (VMA = 13%). In both cases of cracking, the results indicate that the reduction of VMA, and asphalt film thickness throughout the four mixes resulted in an increase in both longitudinal and alligator cracking.

Voids in mineral aggregate (VMA) is an important parameter in hot mix asphalt (HMA) mix design. It is believed that a minimum VMA requirement is necessary to ensure adequate binder content and durability for HMA. This paper investigates the effect of lower than typically acceptable VMA on the load-related cracking resistance of four dense ...

The final mix design should be workable and contain the most suitable gradation and amount of asphalt binder to produce a mix that embodies the best possible combination of all parameters. Mixtures with high VMA are preferred because of the following advantages: (a) More asphalt can be incorporated in the mixture to increase durability.

The low binder content and VMA can have very negative effects on fatigue performance and durability. Mixtures with low binder contents are known to have shortened lives with increased cracking. The lower binder content can affect the compactibility of the mix. The mix may become very difficult to compact during placement.

Jan 01, 1999  A review of asphalt mix design methods indicates that a minimum VMA requirement was not used until the 1950s, when Norman W. McLeod almost single-handedly advanced VMA to a critical design parameter. In 1962, the Asphalt Institute specified VMA as a Marshall mix design requirement, but as late as 1985 it was still misused by many highway agencies.

A critical component of Superpave mix design is the minimum VMA criteria for each different size mix. A 9.5 mm mix has a minimum VMA of 15.0 percent, a 12.5 mm mix is 14.0 percent, and a 19 mm mix is 13.0 percent. Smaller stone mixes have more aggregate surface area to coat, thus requiring more VMA and more asphalt. VMA drives binder content ...

Anderson and Bentsen (26) reported on a study evaluating the influence of voids in mineral aggregate (VMA) on mix- ture performance. Since VMA is related to asphalt binder content, mixtures with high VMA had asphalt binder con- tents that were approximately 1.0% higher than the low VMA mixtures.
