Volumetrics in Asphalt Mixtures

asphalt content of a mix is highly dependent on aggregate characteristics such as gradation and absorptiveness. Aggregate gradation is directly related to optimum asphalt content. The finer the mix gradation, the larger the total surface area of the aggregate and the greater the amount of asphalt required to uniformly coat the particles.

properties of both steel slag and copper tailings, thus, enhanced the volumetric properties and performance of the mixes incorporating both materials. For XRD, the samples were ground into powder form and the test was performed with Siemens D 5000C X-ray Diffractometer. The XRD patterns were scanned one step of

Troubleshooting asphalt mixes | Asphalt magazine

The primary items are air voids and binder volume which combine to become voids in mineral aggregate (VMA). These are all volume proportions of the mix and asphalt binder and aggregate proportions are set to optimize these volumes. Mix Design. Mix design is the basic process of combining aggregate and asphalt binder to produce a strong durable mixture.
