Asphalt mix design

In order to create an asphalt mixture that is deformation resistant, fatigue resistant, low temperature fracture resistant, durable, moisture damage resistant, skid resistant, and workable, the proper aggregates, asphalt binder, and their proportions must be carefully chosen and balanced.

Through established specifications for aggregates, asphalt binder, recycled materials, and volumetric qualities like: Air voids (Pa), Voids in Mineral Aggregate (VMA), Voids Filled with Asphalt (VFA), and dust proportion, the quality of the asphalt mix and its performance are assessed. The parameters are chosen because they historically have given a reliable indicator of how well a mixture would likely work.

It's crucial to comprehend these factors and how they can be impacted during mix manufacture in order to control asphalt mixes both in the lab and on the job site.
