By manipulating the variables of aggregate, asphalt binder and the ratio between the two, mix design seeks to achieve the following qualities in the final HMA product (Roberts et al., 1996): Deformation resistance: HMA should not distort (rut) or deform (shove) under traffic loading. HMA deformation is related to aggregate surface and abrasion

OBJECTIVES OF ASPHALT PAVING MIX DESIGN The design of asphalt paving mixes is largely a matter of selecting and proportioning materials to obtain the desired properties in the finished construction. The overall objective of the design of asphalt paving mixes is to determine an economical blend and gradation of aggregates and asphalt that yields ...
FOR MIX DESIGN TESTING 5.1 Based on the stockpile or bin composite aggregate gradation, the aggregate samples needed for mix design tests are prepared as follows. 5.1.1 Dry the mineral aggregate from each individual stockpile at a temperature not exceeding any temperature restrictions specified in subsequent test procedures.
Superpave Mix Design, D'Angelo 104 2. Materials Selection Binder The design process starts with material selection. The key aspect to the performance of any asphalt mixture is the selection of the optimum materials that will be used in the mixture. One of the key components of Superpave is materials selection.
Controlling asphalt mix designs. Amma Wakefield, P.Eng. 08:52:52. Four tips for controlling asphalt mix designs in the lab and field.

the hot-mix asphalt (HMA) mix design process relate better to actual field performance. Also, a number of agencies have been concerned with the lack of a proof test for validating the volumetric properties. Many have expressed a desire for a truly simple mix test that could be employed at the HMA plant lab level.
Run lab tests to determine key sample characteristics. Pick the asphalt binder content that best satisfies the mix design objectives. Once the optimum asphalt binder content has been determined, the voids in mineral aggregate (VMA) needs to be checked. The owner/agency specifications will indicate the required minimum VMA for your project.
