The effects of different compactors and lift thickness on hot mix asphalt (HMA) have been persistently discussed among asphalt experts. In many cases, pavements paved with the high-in-place air voids permit water to penetrate the permeable pavement c

Several design criteria exist for predicting the fatigue life of hot-mix asphalt (HMA) pavements. Researchers previously developed an Aged Asphalt fatigue criterion from laboratory testing of aged field HMA airfield pavements. This criterion is uniqu

The Alabama Department of Transportation specifies the Superpave® design system for most of its dense-graded HMA mixes. However, there is concern that the number of design gyrations ( NDesign) may be too high for specified traffic levels. Mixes desi

The term "workability" has been used to describe several properties related to the construction of hot-mix asphalt (HMA). For this study, workability was defined as a property describing the ease with which HMA can be placed, worked by hand, and comp
