Troubleshooting asphalt mixes Asphalt magazine

Troubleshooting asphalt mixes. You have just completed an asphalt mix design and are ready to do a plant trial. The mix properties all look good, air voids are on target, VMA (voids in the mineral aggregate) and VFA (voids filled with asphalt) are good. During the plant trial, the mix looks dry, but the binder content and gradation are on target.
